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 Figures 1, 2 and 3 for safe operating curves.

3

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.

4

An external output capacitor is not required for basic operation. Adding

330 µF of distributed capacitance at the load will improve the transient

response.

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

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.

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.
