grated Switching Regulator (ISR).
This ISR allows the integration of
high-speed, low-voltage Pentium pro-
cessors and their support logic into
existing 3.3V or 5V systems without
redesigning the central power supply.
The PT6502 (1.5V) provides the low
terminating voltages required by BTL/
Futurebus+, CTT, HP, and GTL Buses
from existing 3.3V or 5V power rails.

Notes: (1) ISR will operate down to no load with reduced specifications.
(2) The minimum input voltage required by the part is Vout +1.2V or 3.1V, whichever is greater.
(3) For operation below 0°C, use tantalum capacitors. For more information see the related applicatoin note, “PT6000/7000 Series Capacitor
Recommendations.”
(4) See Thermal Derating charts.
Input/Output Capacitors: The PT6500 series requires a 330µF electrolytic or tantalum input and output capacitor for proper operation in all applications. C1 (input)
must be rated for 1.2Arms and 100mΩ max. ESR. C2 (output) must must be rated for 400mArms ripple current and 0.2Ω max. ESR.

The output voltage of the Power Trends PT6500 Series

trimmed pre-set voltage with the addition of a single
external resistor. Table 1 accordingly gives the allowable
adjustment range for each model in the series as Va (min)
and Va (max).

The values of (R1) [adjust down], and R2 [adjust up], can

of the required resistor, either (R1) or R2 as appropriate.

Notes:
1. Use only a single 1% resistor in either the (R1) or R2
location. Place the resistor as close to the ISR as
possible.
2. Never connect capacitors from Vo adjust to either
GND, Vout, or the Remote Sense pin. Any
capacitance added to the Vo adjust pin will affect the
stability of the ISR.
3. If the Remote Sense feature is being used,
connecting the resistor (R1) between pin 14 (Vo
adjust) and pin 1 (Remote Sense) can benefit load
regulation.

Where: Vo = Original output voltage
Va = Adjusted output voltage
Ro = The resistance value in Table 1
Rs = The series resistance from Table 1

higher.

Application Notes
PT6500 Series

Using the Standby Function on the
PT6500 5V/3.3V Bus Converters

Vo(sense)
For applications requiring output voltage On/Off control,
the 14-pin PT6500 ISR series incorporates a standby
function. This function may be used in applications that
require power-up/shutdown sequencing, and wherever
there is a requirement for the output status of the module
to be controlled by external circuitry.

The standby function is provided by the STBY* control,
pin 3. If pin 3 is left open-circuit the regulator operates
normally, and provides a regulated output when a valid
supply voltage is applied to Vin (pins 4, 5, & 6) with re-
spect to GND (pins 7-10). If a low voltage2 is then
applied to pin-3 the regulator output will be disabled and
the input current drawn by the ISR will drop to less than
50mA4. The standby control may also be used to hold-off
the regulator output during the period that input power is
applied.

Turn-On Time: In the circuit of Figure 1, turning Q on applies a
1
low voltage to the Standby control (pin 3) and disables the
regulator ouput. Correspondingly, turning Q1 off releases the
low-voltage signal and enables the output. The PT6500 ISR
series regulators have a fast response and will provide a fully
regulated output voltage within 250 µsec. The actual turn-on
time will vary with load and the total amount of output capaci-
tance. The waveform of Figure 2 shows the typical output
voltage response of a PT6501 (3.3V) following the turn-off of
Q1 at time t = 0.0 secs. The waveform was measured with a
5Vdc input voltage, and 0.6Ω load.
The standby control pin is ideally controlled using an
open-collector (or open-drain) discrete transistor (See
Figure 1). It may also be driven directly from a dedicated
TTL3 compatible gate. Table 1 provides details of the
threshold requirements.

Notes:
1. The Standby/Inhibit control logic is similar for all Power
Trends’ modules, but the flexibility and threshold
tolerances will be different. For specific information on
this function for other regulator models, consult the
applicable application note.
Figure 2
2. The Standby control pin is ideally controlled using an
open-collector (or open-drain) discrete transistor and
requires no external pull-up resistor. The control input has
an open-circuit voltage of about 1Vdc. To disable the
regulator output, the control pin must be pulled to less
than 0.35Vdc with a low-level 0.5mA sink to ground.
3. The Standby input on the PT6500 series may be driven by
a differential output device, making it compatible with
TTL logic. A standard TTL logic gate will meet the
Vo (2V / Div)
0.35V VIL(max) requirement (Table 1 ) at 0.5mA IOL
Do not use devices that can drive the Standby control input
above 5Vdc.

from the input source is reduced to approximately 30–
