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 TurboTransTM technology (patent pending). 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. AutoTrackTM 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.
