DESCRIPTION
The PTV03020W is ready-to-use nonisolated power module, and part of new class of complete dc/dc
switching regulators from Texas Instruments. These regulators 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 PTV03020W series is produced in 12-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 3.3-V
input bus, the series provides step-down conversion to wide range of output voltages, at up to of output
current. The output voltage can be set to any value over the range, 0.8 to 2.5 V, using single external
resistor.
This series includes Auto-Track™. Auto-Track simplifies the task of supply-voltage sequencing in 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. For improved load regulation, an output voltage sense is provided. nonlatching overcurrent trip and
overtemperature shutdown protect against load faults.
Target applications include complex multivoltage, multiprocessor systems that incorporate the industry's
high-speed microprocessors, bus drivers, and the TMS320™ DSP family.
