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 18 A 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, 1.2 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鈩?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.

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

Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
