HV9961
LED Driver with Average-Current Mode Constant-Current Control
Features
General Description
The HV9961 is an Average-Current mode
constant-current control LED driver IC operating in a
constant Off-time mode. Unlike the HV9910B, this
control IC does not produce a peak-to-average error.
This greatly improves accuracy as well as the line and
load regulations of the LED current without any need
for loop compensation or high-side current sensing. Its
output LED current accuracy is ±3%.
• Fast Average Current Control
• Programmable Constant Off-time Switching
• Linear Dimming Input
• PWM Dimming Input
• Output Short-circuit Protection with Skip Mode
•
–40°C to +125°C Ambient Operating
Temperature
• Pin-compatible with HV9910B
The IC is equipped with a current limit comparator for
Hiccup mode output short-circuit protection.
Applications
The HV9961 can be powered from an 8V–450V supply.
It has a PWM dimming input that accepts an external
control TTL-compatible signal. In addition, the output
current can be programmed by an internal 275 mV
reference or controlled externally through a 0V–1.5V
linear dimming input.
• DC/DC or AC/DC LED Driver Applications
• LED Backlight Driver for LCD Displays
• General Purpose Constant-current Source
• LED Signage and Displays
• Architectural and Decorative LED Lighting
• LED Street Lighting
The HV9961 is pin-to-pin compatible with HV9910B,
and it can be used as a drop-in replacement for many
applications to improve LED current accuracy and
regulation.

APPLICATION INFORMATION
General Description
Peak current control (as in HV9910B) is the simplest
and the most economical way to regulate a buck
converter's output current. However, it suffers accuracy
The current through the switching Metal-oxide
Semiconductor Field-effect Transistor (MOSFET)
source is averaged and used to give constant-current
feedback. This current is detected with a sense resistor
at the CS pin. The feedback operates in a fast
Open-loop mode. No compensation is required. Output
current is programmed as seen in Equation 3-2.
and
regulation
problems
that
arise
from
peak-to-average current error, contributed by the
current ripple in the output inductor and the
propagation delay in the current sense comparator.
The full inductor current signal is unavailable for direct
switch current sensing across the sense resistor at the
ground path in this low-side switch buck converter
when the control switch is at the ground potential
because the switch is turned off. While it is very simple
to detect the peak current in the switch, controlling the
average inductor current is usually implemented by
level translating the sense signal from +VIN. Although
this is practical for a relatively low-input voltage, VIN,
this type of average-current control may become
excessively complex and expensive in the offline AC or
other high-voltage DC applications.

When the voltage at the LD input V ≥ 1.5V
LD
If the voltage at the LD input is less than 1.5V, the
output current is computed as specified in
Equation 3-3.
EQUATION 3-3:
The HV9961 uses a proprietary control scheme that
allows fast and accurate control of the average current
in the buck inductor by sensing the switch current only.
No compensation of the current control loop is
required. The output LED current’s response to PWMD
input is similar to that of the HV9910B. The effect of
inductor current ripple amplitude on this control
scheme is insignificant. Therefore, the LED current is
independent of the variation in inductance, switching
frequency or output voltage. Constant off-time control
of the buck converter is used for stability and improving
the LED current regulation over a wide range of input
voltages. Unlike HV9910B, the HV9961 does not
support Constant Frequency mode.

The above equations are only valid for continuous
conduction of the output inductor. It is good design
practice to choose the inductance of the inductor such
that the peak-to-peak inductor current is 30% to 40% of
the average DC full-load current. Hence, the
recommended inductance can be calculated as shown
in Equation 3-4.

The timing resistor connected between RT and GND
determines the off-time of the gate driver. Wiring this
resistor between RT and Gate as with HV9910B is no
longer supported. Refer to Equation 3-1 for the
computation of the gate output’s off-time.
The duty-cycle range of the current control feedback is
limited to D ≤ 0.75. A reduction in the LED current may
occur when the desired LED string voltage VO is
greater than 75% of the input voltage VIN of the
HV9961 LED driver.
EQUATION 3-1:
Reducing the targeted output LED string voltage VO
below VO(MIN) = VIN x DMIN, where DMIN = 1 µs/(TOFF
+1 µs), may also result in the loss of regulation of the
LED current. This condition, however, causes an
increase in the LED current and can potentially trip the
short-circuit protection comparator.

Typical Linear Dimming
The short-circuit protection comparator trips when the
voltage at CS exceeds 0.44V. When this occurs, the
short-circuit gate off-time THICCUP = 400 µs is
generated to prevent the staircasing of the inductor
current and, potentially, its saturation due to insufficient
output voltage. The typical short-circuit inductor current
is shown in the waveform of Figure 3-2.
Response of an HV9961 LED Driver.
The linear dimming input could also be used for
“mixed-mode” dimming to expand the dimming ratio. In
such case, a pulse-width modulated signal with an
amplitude below 1.5V should be applied to LD.
3.5
Input Voltage Regulator
The HV9961 can be powered directly from an
8 VDC–450 VDC supply through its VIN input. When this
voltage is applied at the VIN pin, the HV9961 maintains
a constant 7.5V level at VDD. This voltage can be used
to power the IC and external circuitry connected to VDD
within the rated maximum current or within the thermal
ratings of the package, whichever limit is lower. The
VDD pin must be bypassed by a low ESR capacitor to
provide a low-impedance path for the high-frequency
current of the gate output. The HV9961 can also be
powered through the VDD pin directly with a voltage
greater than the internally regulated 7.5V, but less than
12V.

FIGURE 3-2:
Current.
Short-circuit Inductor
A leading-edge blanking delay is provided at CS to
prevent false triggering of the current feedback and the
short-circuit protection.
Despite the instantaneous voltage rating of 450V,
continuous voltage at VIN is limited by the power
dissipation in the package. For example, when HV9961
draws IIN = 2.5 mA from the VIN input, and the 8-pin
SOIC package is used, the maximum continuous
voltage at VIN is limited to the value shown in
Equation 3-5.
3.4
Linear Dimming
When the voltage at LD falls below 1.5V, the internal
275 mV reference to the constant-current feedback
becomes overridden by VLD x 0.185. As long as the
current in the inductor remains continuous, the LED
current is given by Equation 3-3. However, when VLD
falls below 150 mV, the gate output becomes disabled.
The gate signal recovers when VLD exceeds 200 mV. It
is required in some applications to use the same
brightness control signal input to shut off the lamp. The
typical linear dimming response is shown in Figure 3-3.

In such cases, when it is needed to operate the
HV9961 from a higher voltage, a resistor or a Zener
diode can be added in series with the VIN input to divert
some of the power loss from the HV9961. In the above
example, using a 100V Zener diode will allow the circuit
to work up to 490V. The input current drawn from the
VIN pin is represented by Equation 3-6.

Gate Output
The gate output of the HV9961 is used to drive an
external MOSFET. It is recommended that the gate
charge QG of the external MOSFET be less than 25 nC
for switching frequencies ≤100 kHz and less than
15 nC for switching frequencies >100 kHz.
3.7
PWM Dimming
Due to the fast open-loop response of the
average-current control loop of the HV9961, its PWM
dimming performance nearly matches that of the
HV9910B. The inductor current waveform comparison
is shown in Figure 3-4.

The rising and falling edges are limited by the current
slew rate in the inductor. The first switching cycle is
terminated upon reaching the 275 mV or VLD x 0.185
level at CS. The circuit is further reaching its
steady-state within 3–4 switching cycles regardless of
the switching frequency.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
