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

. 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
