Operating features include an on/off
inhibit, output voltage adjust (trim),
and output over-current protection.
Target applications include telecom,
industrial, and general purpose circuits,
including low-power dual-voltage systems
that use a DSP, microprocessor, or ASIC.
Package options include both through-
hole and surface mount configurations.

ADVANCE INFORMATION
The PTH12000 series of non-isolated
power modules are small in size and high
on performance. Using double-sided sur-
face mount construction and synchronous
rectification technology, these regulators
deliver up to 6 A of output current while
occupying a PCB area of about half the
size of a standard postage stamp. They
are an ideal choice for applications where
space, performance and cost are impor-
tant design constraints.
The series operates from an input
voltage of 12 V to provide step-down
power conversion to any output voltage
over the range, 1.2 V to 5.5 V. The out-
put voltage of the PTH12000W is set
within this range using a single resistor.
