The ultra-wide output voltage trim range offers major advantages to users who
select the PTH05020. 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 PTH05020 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
Notes
1
Remote ON/OFF. Positive Logic
ON:
Pin 3 open; or V > Vin - 0.5 V
OFF:
Pin 3 GND; or V < 0.8 V (min - 0.2 V).

See Figure 1 for safe operating curve.
3
A 1,000 µF electrolytic input capacitor is required for proper operation.
The capacitor must be rated for a minimum of 700 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.

If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).

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
156 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. PTH05020WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH05020WAD.
