The PTH04T240/241W is a high-performance 10-A rated, non-isolated power module. These modules represent

the 2nd generation of the popular PTH series power modules and include a reduced footprint and additional

features. The PTH04T241W is optimized to be used with all ceramic capacitors.

Operating from an input voltage range of 2.2 V to 5.5 V, the PTH04T240/241W requires a single resistor to set

the output voltage to any value over the range, 0.69 V to 3.6 V. The wide input voltage range makes the

PTH04T240/241W particularly suitable for advanced computing and server applications that utilize a 2.5-V,

3.3-V, or 5-V intermediate bus architecture.

The module incorporates a comprehensive list of features. Output over-current 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.
