The PTV03020W is a ready-to-use nonisolated power module, and part of a 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 a 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 a 3.3-V input bus, the series provides step-down conversion to a wide range of output voltages, at up to 18 A of output current. The output voltage can be set to any value over the range, 0.8 V to 2.5 V, using a single external resistor.
