DESCRIPTION  
The PTH08T255W is a high-performance 40-A rated, non-isolated power module. This module represents the  
2nd generation of the popular PTH series power modules with a reduced footprint and improved features.  
Operating from an input voltage range of 8 V to 14 V, the PTH08T255W requires a single resistor to set the  
output voltage to any value over the range, 3.0 V to 5.25 V. The wide input voltage range makes the  
PTH08T255W particularly suitable for advanced computing and server applications that utilize a loosely  
regulated 9.6-V to 12-V intermediate distribution bus.  
The module incorporates a comprehensive list of features. Output overcurrent and over-temperature shutdown  
protects against most load faults. A differential remote sense ensures tight load regulation. An adjustable  
under-voltage lockout allows the turn-on voltage threshold to be customized. Auto-Track™ sequencing is a  
popular feature that greatly simplifies the simultaneous power-up and power-down of multiple modules in a  
power system. Additionally, the capability to current share between multiple PTH08T255W modules allows for  
load currents greater than 40A on a single rail.  
The PTH08T255W includes new patented technologies, TurboTrans™ and SmartSync. The TurboTrans feature  
optimizes the transient response of the regulator while simultaneously reducing the quantity of external output  
capacitors required to meet a target voltage deviation specification. Additionally, for a target output capacitor  
bank, TurboTrans can be used to significantly improve the regulators transient response by reducing the peak  
voltage deviation. SmartSync allows for switching frequency synchronization of multiple modules, thus simplifying  
EMI noise suppression tasks and reducing input capacitor RMS current requirements.  
The module uses double-sided surface mount construction to provide a low profile and compact footprint.  
Package options include both through-hole and surface mount configurations that are lead (Pb) - free and RoHS  
compatible.
