The PTH12020 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 95%. The PTH12020
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 560 F 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 F of distributed capacitance at the load will improve the transient
response.

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.
