Output Voltage Adjustment of the PTH03030 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH03030. 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 2.5 Vdc. When the PTH03030 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.

A 1,500 µF electrolytic input capacitor is required for proper operation.
The capacitor must be rated for a minimum of 900 mA rms of ripple
current.
An external output capacitor is not required for basic operation. Adding
330 µF of distributed capacitance at the load will improve the transient
response.

and will sink current if the output voltage is below that of a back-feeding
source. Therefore to ensure a pre-bias hold-off, one of the following two
techniques must be followed when input power is first applied to the

module. The Auto-Track function must either be disabled, or the
module’s output held off using the Inhibit pin. Refer to Application Note
152 for more details.
Tape and reel packaging only available on the surface-mount versions.
To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH03030WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH03030WAD.
