PTV05010W中文资料具有自动跟踪功能的 8A 5V 输入非隔离宽输出调节 SIP 模块数据手册TI规格书

描述 Description

The PTV05010W 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 PTV05010W 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 5-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 3.6 V, 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. 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.
