Output Voltage Adjustment of the PTH04040W Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH04040W. 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 2.5 Vdc. When the PTH04040W converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
Notes
The set-point voltage tolerance is affected by the tolerance and stability
of R
SET
. The stated limit is unconditionally met if R
SET
has a tolerance of
1% with 100 ppm/ºC or better temperature stability.

This control pin has an internal pull-up to Vin nominal. If it is left open-
circuit the module will operate when input power is applied. A small low-
leakage (<100 nA) MOSFET is recommend for control. For further
information, consult Application Note 192.
3
A 1000 µF input capacitor is required for proper operation. The capacitor
must be rated for a minimum of 400 mA rms of ripple current.
4
This is with a 1 A/µs loadstep, 50 to 100% I
omax
. C
o
= 660 µF.
5
The minimum input voltage is 2.95 V or 1.34 x V
o
, whichever is greater.
6
These are default voltages. They may be adjusted using the ‘UVLO Prog.’
control input. Consult Application Note 192 for further details.
7
See Figures 1 and 2 for safe operating curves. All power pins must be
used.
8
A small low-leakage (<100 nA) MOSFET is recommended to control this
pin. The opencircuit voltage is less than 1 Vdc.
9
To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH04040WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH04040WAD.
