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 F electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 750 mA rms of ripple current.
C2 = 10 F ceramic capacitor, required for output voltages of 3.3 V and
higher.
4
An external output capacitor is not required for basic operation. Adding
100 F of distributed capacitance at the load will improve the transient
response.
5
1 A/s load step, 50 to 100% Iomax, Cout = 100 F.
6
If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).
7
Tape and reel packaging only available on the surface-mount versions.
8
The pk-pk output ripple voltage is measured with an external 10F
ceramic capacitor. See Figure 3 Standard application schematic.

To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH12050WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH12050WAD.
10 NOTICE: Some models do not support all options. Please contact your
local Artesyn 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 PTH12050. 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 V to 5.5 V for suffix ‘-W’ and 0.8 V to 1.8 V for suffix ‘-L’.
When the PTH12050 converter leaves the factory the output has been adjusted
to the default voltage of 1.2 V for the PTH12050W and 0.8V for the
PTH12050L.
