Output Voltage Adjustment of the PTH12020 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH12020. 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. When the PTH12020 converter
leaves the factory the output has been adjusted to the default voltage of 1.2 V.

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).
See Figures 1, 2 and 3 for safe operating curves.
A 560 µF electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 800 mA rms of ripple current.
An external output capacitor is not required for basic operation. Adding
330 µF of distributed capacitance at the load will improve the transient
response.

If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).
Tape and reel packaging only available on the surface-mount versions.
To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH12020WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH12020WAD.
