●The PTV05020W 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 PTV05020W 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 5-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 3.6 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. For improved load regulation, an output voltage sense is provided. A nonlatching overcurrent trip and overtemperature shutdown protects against load faults.
●Target applications include complex multivoltage, multiprocessor systems that incorporate the industry"s high-speed DSPs, microprocessors, and bus drivers.
