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).

2

See Figure 1 for safe operating curve.

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

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-

the Inhibit pin. Refer to Application Note 158 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. PTH05050WAZ. To order Pb-free (RoHS compatible)

through-hole parts replace the mounting option ‘H’ with ‘D’, e.g.

PTH05050WAD.

10 NOTICE: Some models do not support all options. Please contact your local sales

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

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.
