描述 Description

The PTH03010 series of non-isolated

power modules are small in size but big on

performance and flexibility. Their high

output current, compact footprint, and

industry-leading features offers system

designers a versatile module for powering

complex multi-processor digital systems.

The series employs double-sided surface

mount construction and provides highperformance

step-down power conversion

for up to 15 A of output current from a

3.3-V input bus voltage. The output voltage

of the PTH03010W 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?.

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 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.
