NEW Product
File Name: pth12040w.pdf Rev (03): 19 Dec 2005
The PTH12040 is a next generation series of non-isolated dc-dc converters offering
some of the most advanced POL features available in the industry. The primary new
feature provides for sequencing between multiple modules, a function, which is
becoming a necessity for powering advanced silicon including DSP's, FPGA's and
ASIC's requiring controlled power-up and power-down Other industry leading
features include margin up/down controls and efficiencies up to 96%. The
PTH12040 has an input voltage of 8 Vdc to 14 Vdc and offers a wide 0.8 Vdc to
5.5 Vdc output voltage range with up to 50 A output current, which allows for
maximum design flexibility and a pathway for future upgrades.

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/C or better temperature stability.
2
This control pin has an internal pull-up to 5 V nominal. If it is left open-
circuit the module will operate when input power is applied. A small
lowleakage (<100 nA) MOSFET is recommended for control. For further
information, consult the related application note. For further information,
consult Application Note 193.
3
A 1000 F input capacitor is required for proper operation. The capacitor
must be rated for a minimum of 300 mA rms of ripple current.
4
This is with a 1 A/s loadstep, 50 to 100% I
omax
. I
o
= 680 F
5
See Figures 1 and 2 for safe operating curves.
6
When the set-point voltage is adjusted higher than 3.6 V, a 10 V minimum
input voltage is recommended.
7
A small low-leakage (<100 nA) MOSFET is recommended to control this
pin. The opencircuit voltage is less than 1 Vdc.
8
These are the default voltages. The y may be adjusted using the `UVLO
Prog' control input. Consult Application Note No. 193 for further
information.
9
To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option `S' with `Z', e.g. PTH12040WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option `H'
with `D', e.g. PTH12040WAD.

The ultra-wide output voltage trim range offers major advantages to users who
select the PTH12040W. 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 5.5 Vdc. When the PTH12040W converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
