DESCRIPTIONThe PTH08T260/261Wis the higher input voltage (4.5Vto 14V) versionof the PTH04T260/261W (2.2Vto 5.5V),
3-A rated, non-isolated power module. This regulator represents the 2nd generationof the PTH seriesof power
modules which includea reduced footprint and improved features. The PTH08T261Wis optimizedto be usedin
applications requiringall ceramic capacitors.
Operating froman input voltage rangeof 4.5Vto 14V, the PTH08T260/261W requiresa single resistorto set the
output voltage to any value over the range, 0.69V to 5.5V. The wide input voltage range makes the
PTH08T260/261W particularly suitable for advanced computing and server applications that usea loosely distribution bus. Additionally, the wide input voltage range increases design tightly regulated 5-V, 8-V,or 12-V intermediate bus architectures.a listof features. Output over-current and over-temperature shutdown load faults.A differential remote sense ensures tight load regulation.
