描述 Description

The PTH03060W non-isolated power

module is small in size but big on performance

and flexibility. Its high output

current, compact footprint, and industryleading

features offers system designers

a versatile module for powering complex

multi-processor digital systems.

This product employs double-sided

surface mount construction and provides

high-performance step-down power

conversion for up to 10 A of output current

from a 3.3-V input bus voltage.

The output voltage is adjustable and can

be set to any value over the range, 0.8 V to

2.5 V, using a single resistor.

This series includes Auto-Track?

Sequencing. 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, margin up/down controls,

and the ability to start up into an existing

output voltage or prebias. To ensure tight

load regulation, an output voltage sense

is also provided. A non-latching overcurrent

trip serves as 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.
