The PTH12010 series of non-isolated power modules that are small in size but big on performance and

flexibility. The high output current, compact footprint, and industry-leading features offers system designers a

versatile module for powering complex multi-processor digital systems.

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

conversion for up to 12 A of output current. 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 devices have an adjustment range of 0.8 V to 1.8 V. The output voltage is

set using a single external resistor.

This series includes Auto-Track™ sequencing. Auto-Track 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 also provided. A nonlatching overcurrent trip serves as load fault protection.

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

high-speed TMS320™ DSP family, microprocessors, and bus drivers.
