Output Voltage Adjustment of the PTH12020 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH12020. 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 1.2 Vdc to 5.5 Vdc. When the PTH12020 converter leaves the factory the
output has been adjusted to the default voltage of 1.2 V.

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 Figures 1, 2 and 3 for safe operating curves.
A 560 µF electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 800 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.

If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).
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. PTH12020WAZ. To order Pb-free (RoHS
compatible) through-hole parts replace the mounting option ‘H’ with ‘D’, e.g.
PTH12020WAD.
NOTICE: Some models do not support all options. Please contact your local
Emerson Network Power representative or use the on-line model number search
tool at http://www.Emerson.com/EmbeddedPower to find a suitable alternative.
