DESCRIPTION
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.
