PTH04T240F数据手册电源-板安装的直流转换器规格书PDF

描述 Description

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 PTH04T240Fincludesnew 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 synchronizationof 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.
