DESCRIPTION

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.

The PTH04T240/241W includes new patent pending 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.
