Output Voltage Adjustment

The ultra-wide output voltage trim range offers major advantages to users who

select the PTH12050. It is no longer necessary to purchase a variety of

modules in order to cover different output voltages. The output voltage can be

trimmed in a range of 1.2 Vdc to 5.5 Vdc for suffix ‘W’ and 0.8 Vdc to 1.8 Vdc

for suffix ‘L’. When the PTH12050 converter leaves the factory the output has

been adjusted to the default voltage of 1.2 V for the PTH12050W and 0.8 V for

the PTH12050L.

Notes:

1. Remote ON/OFF. Positive Logic

ON: Pin 3 open; or V > Vin - 0.5 V

OFF: Pin 3 GND; or V < 0.8 V (min - 0.2 V).

2. See Figure 1 for safe operating curve.

3. A 100 μF electrolytic input capacitor is required for proper operation. The capacitor must be

rated for a minimum of 750 mA rms of ripple current. C2 = 10 μF ceramic capacitor, required

for output voltages of 3.3 V and higher.

4. An external output capacitor is not required for basic operation. Adding 100 μF of distributed

capacitance at the load will improve the transient response.

5. 1 A/μs load step, 50 to 100% Iomax, Cout = 100 μF.

6. If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).

7. Tape and reel packaging only available on the surface-mount versions.

8. The pk-pk output ripple voltage is measured with an external 10 μF ceramic capacitor. See

Figure 3 for Standard application schematic.
