DESCRIPTION

The PTH12020 series of non-isolated power modules offers OEM designers a combination of high performance,

small footprint, and industry leading features. As part of a new class of power modules, these products provide

designers with the flexibility to power the most complex multi-processor digital systems using off-the-shelf catalog

parts.

The series employs double-sided surface mount construction and provides highperformance step-down power

conversion for up to 18A of output current from a 12-V input bus voltage. The output voltage of the W-suffix parts

can be set to any value over the range, 1.2V to 5.5V. The L-suffix parts have an adjustment range of 0.8V to

1.8V. The output voltage is set using a single resistor.

This series includes Auto-Track™ sequencing. Auto-Track sequencing 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), margin up/down

controls, and the ability to start up into an existing output voltage or prebias. For improved load regulation, an

output voltage sense is provided. A non-latching over-current trip and overtemperature shutdown feature protects

against load faults.

Target applications include complex multivoltage, multiprocessor systems that incorporate the industry's

high-speed DSPs, microprocessors and bus drivers.

For start-up into a non-prebiased output, review page 14 in the Application Information section.

For start-up into a prebiased output, review page 18 in the Application Information section.

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.
