Description

The PTH05010 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 high-

performance step-down power conversion

for up to 15 A of output current from a

5-V input bus voltage. The output volt-

age of the PTH05010W 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 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.
