Description
The PTH03030 is a series of high-
current non-isolated power modules
from Texas Instruments. The product is
characterized by high efficiencies, and
up to 30 A of output current, while oc-
cupying a mere 1.64 in 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 mixed-
signal 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 high-
performance step-down power conversion
from a 3.3-V input bus voltage. The out-
put voltage of the PTH03030W 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 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 through-
hole and surface mount configurations.
