描述 Description

The PTH05030 is a series of highcurrent

non-isolated power modules

from Texas Instruments. This product is

characterized by high efficiencies, and

up to 30 A of output current, while occupying

a mere 1.64 in² of PCB area. In

terms of cost, size, and performance, the

series provides OEM’s with a flexible

module that meets the requirements of

the most complex and demanding mixedsignal

applications. These include the

most densly populated, multi-processor

systems that incorporate high-speed

DSP’s, microprocessors, and ASICs.

The series uses double-sided surface

mount construction and provides highperformance

step-down power conversion

from a 5-V input bus voltage. The output

voltage of the PTH05030W 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 power-up and

power-down supply voltage sequencing

in a system by enabling modules to track

each other, or any other external voltage.

Each model also includes an on/off

inhibit, output voltage adjust (trim), and

margin up/down controls. An output

voltage sense ensures tight load regulation,

and an output over-current and thermal

shutdown feature provide for protection

against external load faults.

Package options inlude both throughhole

and surface mount configurations.
