描述 Description

The PTH05020 series of non-isolated

power modules offers OEM designers a

combination of high performance, small

footprint, and industry leading features.

As part of a new class of power modules

these products provide designers with the

flexibility to power the most complex

multi-processor digital systems using

off-the-shelf catalog parts.

The series employs double-sided surface

mount construction and provides highperformance

step-down power conversion

for up to 22 A of output current from a

5-V input bus voltage. The output voltage

of the PTH05020W can be set to

any value over the range, 0.8 V to 3.6 V,

using a single resistor.

This series includes Auto-Track™.

Auto-Track simplifies the task of supply

voltage sequencing in a power system by

enabling modules to track each other, or

any external voltage, during power up and

power down.

Other operating features include an

on/off inhibit, output voltage adjust (trim),

and margin up/down controls. To ensure

tight load regulation, an output voltage

sense is also provided. A non-latching

over-current trip and over-temperature

shutdown provides load fault protection.

Target applications include complex

multi-voltage, multi-processor systems

that incorporate the industry’s high-speed

DSPs, micro-processors and bus drivers.
