描述 Description

The PTH05000 series of non-isolated

power modules are small in size and high

on performance. Using double-sided surface

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 important

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 output

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-temperature

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 during

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 throughhole

and surface mount configurations.
