switching regulators from Texas Instruments. These regulators PTV03010W 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 PTV03010W series is produced in a 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 3.3-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 can be set to any value over the range, 0.8 V to 2.5 V. The output voltage is set using a single external resistor.

This PTV03010W 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 PTV03010W features include an on/off inhibit, and the ability to start up into an existing output voltage or prebias. A nonlatching overcurrent trip protects 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.
