The PTV12010 series of non-isolated power modules are part of a new class of complete dc/dc switching
regulator modules from Texas Instruments. These modules combine high performance with double-sided,
surface mount construction to give designers the flexibility to power the most complex multiprocessor digital
systems using off-the-shelf catalog parts.
The PTV12010 series is produced in an 8-pin, single in-line pin (SIP) package. The SIP footprint minimizes
board space, and offers an alternate package option for space conscious applications. Operating from a 12-V
input bus, the series provides step-down conversion to a wide range of output voltages, at up to 8 A of output
current. The output voltage of the W-suffix parts can be set to any value over the range of 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 external
resistor.
This series includes Auto-Track™. Auto-Track™ simplifies the task of supply-voltage sequencing in a power
system by enabling the output voltage of multiple modules to accurately track each other, or any external
voltage, during power up and power down.
Other operating features include an on/off inhibit, and the ability to start up into an existing output voltage or
prebias. A nonlatching overcurrent trip and overtemperature shutdown provide protection against load faults.
Target applications include complex multivoltage, multiprocessor systems that incorporate the industry's
high-speed DSPs, microprocessors, and bus drivers.
