Advanced Pulse-width Modulation (pwm) Controller For Home Gateways

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 set-top box, cable modem, DSL modem and residential home gateway core processor, memory and peripheral power supplies. This device 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. The ISL6431 provides simple, single feedback loop, voltage- mode control with fast transient response. The output voltage CAN be precisely regulated to as low as 0.8V, with a maximum tolerance of 1.5% over temperature and line voltage variations. A fixed frequency Oscillator reduces design complexity, while balancing typical application cost and efficiency. By Intersil Corporation
