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.

ON:
Pin 4 open; or V > Vin - 0.5 V
OFF:
Pin 4 GND; or V < 0.8 V (min - 0.2 V).

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.

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.
