描述 Description

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 to8 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 anon/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.
