Output Voltage Adjustment of the PTH05050 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH05050. 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 0.8 Vdc to 3.6 Vdc. When the PTH05050 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.

A 100 µF electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 300 mA rms of ripple current.
An external output capacitor is not required for basic operation. Adding
100 µF of distributed capacitance at the load will improve the transient
response.

To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH05050WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH05050WAD.
