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.
