Texas Instruments  PTV08T250WAD

The PTV08T250W is a high-performance 50-A rated, non-isolated, vertical power module which uses a multi-phase switched-mode topology. This provides a small, ready-to-use module that can power the most densely populated multiprocessor systems. The PTV08T250W is produced in a 21-pin, single in-line pin (SIP) package. The SIP footprint minimizes board space, and offers an alternate package option for space conscious applications. The modules use double-sided surface mount construction to provide a compact design.

Operating from an input voltage range of 8 V to 14 V, the PTV08T250W requires a single resistor to set the output voltage to any value over the range, 0.8 V to 3.6 V. The wide input voltage range makes the PTV08T250W suitable for advanced computing and server applications that use a loosely regulated 12-V intermediate distribution bus.

A new feature included in this 2nd generation of PTH and PTV modules is TurboTrans™ technology. TurboTrans allows the transient response of the regulator to be optimized externally, resulting in a reduction of output voltage deviation following a load transient and a reduction in required output capacitance. This feature also offers enhanced stability when used with ultra-low ESR output capacitors.

The PTV08T250W incorporates a comprehensive list of standard features. They include on/off inhibit, a differential remote output voltage sense which ensures tight load regulation, and an output overcurrent and overtemperature shutdown to protect against load faults. A programmable undervoltage lockout allows the turn-on and turn-off voltage thresholds to be customized. AutoTrack™ sequencing is a popular feature which greatly simplifies the simultaneous power-up and power-down of multiple modules in a power system by allowing the outputs to track a common voltage.
