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.

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 10µF

ceramic capacitor. See Figure 3 Standard application schematic.

To order Pb-free (RoHS compatible) surface-mount parts replace the

mounting option ‘S’ with ‘Z’, e.g. PTH12050WAZ. To order Pb-free

(RoHS compatible) through-hole parts replace the mounting option ‘H’

with ‘D’, e.g. PTH12050WAD.

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 V to 5.5 V for suffix ‘-W’ and 0.8 V to 1.8 V 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 0.8V for the

PTH12050L.
