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.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

Output Voltage Adjustment of the PTH12020 Series
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.

ON:
Pin 3 open; or V > Vin - 0.5 V
OFF:
Pin 3 GND; or V < 0.8 V (min - 0.2 V).
See Figures 1, 2 and 3 for safe operating curves.
A 560 µF 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 µF of distributed capacitance at the load will improve the transient
response.

Tape and reel packaging only available on the surface-mount versions.
To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH12020WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH12020WAD.
