SGM6036
450nA Ultra-Low Power, Buck Converter
with 600mA Output Current
GENERAL DESCRIPTION
FEATURES
The SGM6036 family is a 600mA, 1.4MHz synchronous
Buck DC/DC converter with 450nA ultra-low quiescent
current, which is ideal for powering ultra-low power
applications with special needs.
● Input Voltage Range: 1.8V to 5.5V
● Fixed Output Voltages: 1.0V, 1.2V and 3.3V
● Adjustable Output Voltages: 1.0V to 3.3V
● High Efficiency at Low Output Currents:
Up to 90% with IOUT = 0.1mA
The SGM6036 operation voltage range is from 1.8V to
5.5V, allowing the use of a regulated 5V input. The
SGM6036 is available in both adjustable and fixed
output voltage versions. The output voltage of
SGM6036 can be programmed by an external resistor
divider in adjustable version.
● Ultra-Low Power Buck Converter
● 600mA (MAX) Output Current
● 450nA (TYP) Quiescent Current
● 100% Duty Cycle (Pass Mode)
● -40℃ to +85℃ Operating Temperature Range
● Available in a Green UTDFN-1.5×2-6L Package
The SGM6036 delivers an output current of 600mA with
a peak inductor current of 940mA. Besides, the
SGM6036 series has the under-voltage lockout (UVLO)
function. It is disabled when the voltage on VIN reaches
the UVLO condition. The SGM6036’s under-voltage
lockout level is continuously monitored. Only the
inductor, CIN and COUT capacitors are needed as
external components to make a Buck DC/DC converter
solution.

450nA Ultra-Low Power, Buck Converter
with 600mA Output Current
SGM6036
DETAILED DESCRIPTION
The SGM6036 family is a synchronous Buck converter
with ultra-low quiescent current of 450nA (TYP). The
device is improved to provide high efficiency ranging
Under-Voltage Lockout (UVLO)
The device monitors the input voltage and shuts down
itself when the input voltage is lower than UVLO
threshold voltage. When the input voltage is higher
than the UVLO threshold plus hysteresis, the device
will start again.
from 10μA to 600mA.
The SGM6036 implements the hysteretic control
architecture to regulate the output voltage. The 450nA
(TYP) quiescent current extends the operation lifetime
for battery operated applications.
Thermal Shutdown (TSD)
A thermal shutdown function is implemented to prevent
the damage caused by excessive heat and power
dissipation. Once a temperature of +160°C (TYP) is
exceeded, the device is shut down. The device is
released from shutdown automatically when the
junction temperature decreases by 20℃.
Operation
The SGM6036 family is a Buck converter that is
capable to regulate the voltage that is lower than the
input voltage at the output. The device implements the
pulse frequency modulation (PFM) control to regulate
the voltage at light load. The SGM6036 delivers an
average output current of 600mA with a peak inductor
current of 940mA (TYP). The device implements an
input under-voltage lockout (UVLO) function. When the
input voltage drops below the UVLO threshold, the
device stops operation. In addition to input UVLO
function, the SGM6036 also implements the EN pin to
allow external signal to control the turn-on and turn-off
of the device. The device also implements output
discharge function, when the EN pin is pulled to logic
low, the low-side power FET remains on to discharge
the output voltage. The SGM6036 also implements 100%
duty cycle mode to bypass the input voltage to the
output when the input voltage is above the UVLO
threshold.
Nano-Power Management and Efficiency
The SGM6036 implements the nano-power circuitry
and algorithm to achieve 450nA (TYP) quiescent
current. This feature is accomplished through sampling
and all references are saved, so as to lower the
average quiescent current. During the sampling and
saving, the internal circuits are only turned on for a
short period of time and then turned off in the remaining
time at the lowest feasible duty cycle.

with 600mA Output Current
SGM6036
APPLICATION INFORMATION
The SGM6036 family has ultra-low quiescent current
and is capable of delivering up to 600mA load current,
which is suitable for battery operated applications.
Inductor Selection
The SGM6036 is optimized to work with a 4.7μH
inductor. The selected inductor’s saturation current
should be at least 25% higher than the maximum
cycle-by-cycle current limit specified in the Electrical
Characteristics table. The SGM6036 is naturally stable
due to its hysteretic control architecture.
Setting the Output Voltage
The output voltage is set by a resistor divider between
the output voltage and the FB pin. The voltage divider
divides the output voltage down to the feedback voltage
by the ratio:
The recommended inductors for SGM6036 are shown
in Table 1.

Output Capacitor Selection
The value for R2 can be as high as 1MΩ.
A minimal of 22μF ceramic output capacitor is
recommended for SGM6036. Larger size will result in
higher effective capacitance under the same DC
de-rating, which improves the transient response and
output ripple.
For example, for a 2V output voltage, R2 is 1MΩ, and
R1 is 1MΩ.
Design Procedure
A 4.7μH inductor and a 22μF input ceramic capacitor
are recommended for the SGM6036. Since the device
only supports 600mA output load, a 22 μ F output
ceramic capacitor is sufficient. For applications that are
Input Capacitor Selection
A 22μF ceramic capacitor and a 0.1μF ceramic bypass
input capacitor are recommended to place between the
VIN pin and GND as close as possible to minimize the
parasitic inductance. For applications where the
SGM6036 is located far away from the input source, a
22µF or higher capacitor is recommended to damp the
inductance of the wiring harness.
expected to have a large transient event, use ITRAN

accordingly, where ΔVOUT is the amount of output
voltage drop during load step.
