SPECIFICATIONS
The PTH12050 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 efficiencies up to 93%. The PTH12050 has an input voltage of 10.8 Vdc to
13.2 Vdc
and offers a wide output voltage range adjustable with external trim resistor,
allowing for maximum design flexibility and a pathway for future upgrades.

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.

1 A/s load step, 50 to 100% Iomax, Cout = 100 F.

If utilized Vout will track applied voltage by 0.3 V (up to Vo set point).

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.

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.
