PTH04T240FAZ

10 -A ， 2.2 V至5.5 V输入，非隔离式电源模块，用于3 GHz的DSP系统 10-A, 2.2-V to 5.5-V INPUT, NON-ISOLATED POWER MODULE FOR 3-GHz DSP SYSTEMS

The PTH04T240F is a high-performance 10-A rated, non-isolated power module designed to meet ultra-fast transient requirements for 3-GHz DSP systems like Texas Instruments" TMS320TCI6488. This module is an addition to the 2nd generation of the popular PTH series power modules which include a reduced footprint and additional features.

Operating from an input voltage range of 2.2 V to 5.5 V, the PTH04T240F requires a single resistor to set the output voltage to any value over the range, 0.69 V to 2.0 V. The output voltage range makes the PTH04T240F particularly suitable for the 3-GHz DSP"s core voltage requirements.

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 PTH04T240F 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. TurboTrans allows the PTH04T240F to meet the tight transient voltage tolerances required by 3-GHz DSPs with minimal output capacitance. 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.
