DESCRIPTION
The PTV08040W is a high-performance 50-A rated, non-isolated, power module, that uses the latest multi-phase
switched-mode topology. This provides a small, ready-to-use module, that can power the most densely populated
multiprocessor systems. The PTV08040W 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 low profile and compact footprint.
Operating from an input voltage range of 8 V to 14 V, the PTV08040W 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 PTV08040W
particularly suitable for advanced computing and server applications that utilize a loosely regulated intermediate
distribution bus of 8 V to 14 V.
The PTV08040W incorporates Auto-Track™ sequencing. The Auto-Track feature of the PTH and PTV family
allows the outputs of multiple modules to track a common voltage during power up and power down transitions.
This simplifies power up and power down supply-voltage sequencing in a power supply system.
The module incorporates a comprehensive list of 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. The programmable undervoltage lockout allows the turn-on and turn-off voltage
thresholds to be customized.
