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 puting and server applications that utilize a loosely regulated 9.6-V to 12-V intermediate distribution bus. The module incorporates a prehensive 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, Turbo Trans™ and Smart Sync. The Turbo Trans feature optimizes the...
