Description

The PTH05000 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 5 V to provide step-down

power conversion to any output voltage

over the range, 0.9 V to 3.6 V. The out-

put voltage of the PTH05000W is set

within this range using a single resistor.

Operating features include an on/off

inhibit, output voltage adjust (trim), an

output current limit, and over-tempera-

ture protection.

For high efficiency these parts employ

a synchronous rectifier output stage. An

output pre-bias holdoff capability ensures

that the output will not sink current dur-

ing startup.

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.
