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鈩?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.

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
