Single Synchronous Buck Regulator with Integrated FET for WLAN Chipsets
Overview
Description
The ISL6410, ISL6410A are synchronous current-mode PWM regulators designed to provide a total DC/DC solution for microcontrollers, microprocessors, CPLDs, FPGAs, core processors/BBP/MAC, and ASICs. The ISL6410 should be selected for applications using 3.3V ±10% as an input voltage and the ISL6410A in applications requiring 5.0V ±10%. These synchronous current mode PWM regulators have integrated N- and P-Channel power MOSFETs and provide pre-set pin programmable outputs. Synchronous rectification with internal MOSFETs is used to achieve higher efficiency and a reduced external component count. The operating frequency of 750kHz typical allows the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 500kHz to 1MHz. A power good signal PG is generated when the output voltage falls outside the regulation limits. Other features include overcurrent protection and thermal overload shutdown. The ISL6410, ISL6410A are available in an MSOP 10 lead package.
