ISL6431
Advanced Pulse Width Modulation (PWM) Controller for Broadband Applications
FN9018 Rev 1.00 Jun 2002
The ISL6431 is a high efficiency, fixed frequency, synchronous buck PWM controller. It is designed for use in applications that convert 5V to lower distributed voltages required for DSL modems, cable and DSL routers and broadband gateway core processor, memory and peripheral power supplies.
The ISL6431 makes simple work out of implementing a complete control and protection scheme for a DC-DC stepdown converter. Designed to drive N-channel MOSFETs in a synchronous buck topology, the ISL6431 integrates the control, output adjustment, monitoring and protection functions into a single 8-pin package.
