ON:

Pin 4 open; or V > Vin - 0.5 V

OFF:

Pin 4 GND; or V < 0.8 V (min - 0.2 V).

See Figure 1 for safe operating curve of the PTH12030W and Figure 4 for

safe operating curve of PTH12030L

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

The pk-pk output ripple voltage is measured with an external 10µF

ceramic capacitor. See Figure 3 Standard application schematic on the

following page.

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

mounting option ‘S’ with ‘Z’, e.g. PTH12030WAZ. To order Pb-free

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

with ‘D’, e.g. PTH12030WAD.

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

select the PTH12030. 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 PTH12030 converter leaves the factory the output has

been adjusted to the default voltage of 1.2 V for the PTH12030W and 0.8V for

the PTH12030L.
