Single Synchronous Buck Pulse-Width Modulation (PWM) Controller

The ISL6520B makes simple work out of implementing a complete control scheme for a DC/DC stepdown converter. Designed to drive N-Channel MOSFETs in a synchronous buck topology, the ISL6520B integrates the control, output adjustment and monitoring functions into a single 8 Lead package.
The ISL6520B 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.
The error Amplifier features a 15MHz gain-bandwidth product and 8V/s slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty cycles range from 0% to 100%.
