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.
