3 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.
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.

6 If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).
7 The pre-bias start-up feature is not compatible with Auto-Track
™
. This is
because when the module is under Auto-Track
™
control, it is fully active 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 158 for more details
.
8 Tape and reel packaging only available on the surface-mount versions.
9 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.

representative or use the on-line model number search tool at

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.
