DESCRIPTION

The PTH04040W is a high-performance 60-A rated, nonisolated, power module, which 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 PTH04040W operates over an input voltage range of 2.95 V to 5.5 V, and can be set to any output voltage

over the range, 0.8 V to 2.5 V, using a single external resistor. The combination of a wide input voltage and

wide-output adjust range allows the PTH04040W to be used in many of high-performance applications. These

include advanced computing platforms and servers that utilize either a 3.3-V or 5-V distribution bus.

These modules incorporate a comprehensive list of features. They include an on/off inhibit and margin up/down

controls. A differential remote output voltage sense ensures tight load regulation, and an output overcurrent and

overtemperature shutdown protect against most load faults. A programmable undervoltage lockout allows the

turn-on threshold to be customized.

The PTH04040W incorporates Auto-Track™. Auto-Track is a popular feature of the PTH family that allows the

outputs of multiple modules to track a common voltage during power-up and power-down transitions. This greatly

simplifies the sequencing of voltages for VLSI ICs that operate off multiple power rails.

The double-sided surface mount construction has a low profile and compact footprint. It is available in both

throughhole and surface-mount packages.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

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

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
