Description
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 volt-
age of 12 V to provide step-down power
conversion to a wide range of output volt-
ages. W-suffix devices are adjustable from
1.2 V to 5.5 V, and L-suffix devices are
adjustable from 0.8 V to 1.8 V. The out-
put voltage is set within the adjustment
range using a single external resistor.
Operating features include an on/off
inhibit, output voltage adjust (trim), and
the ability to start up into an existing
output voltage or prebias. A non-latching
over-current trip provides protection
against load faults.
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.
