DESCRIPTION
The PTH12030 is a series of high current, non-isolated power module from Texas Instruments. This product is
characterized by high efficiencies, and up to 26 A of output current, while occupying a small PCB area of
1.64 in
2
. 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, multiprocessor systems that incorporate the high-speed TMS320™ DSP family, microprocessors,
and ASICs.
The series uses double-sided surface mount construction and provides high-performance step-down power
conversion from a 12-V input bus voltage. The output voltage of the W-suffix parts can be set to any value over
the range, 1.2 V to 5.5 V. The L-suffix parts have an adjustment range of 0.8 V to 1.8 V. The output voltage is
set 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, and the
ability to start up into an existing prebias. An output voltage sense ensures tight load regulation, and an output
overcurrent and thermal shutdown feature provide for protection against external load faults.
Package options inlude both through-hole and surface mount configurations.
