Buck And Synchronous Rectifier Pulse-Width Modulator (PWM) Controller

The ISL6522A provides complete control and protection for a DC-DC Converter optimized for high-performance Microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous rectified buck topology. The ISL6522A integrates all of the control, output adjustment, monitoring and protection functions into a single package.
The output voltage of the converter CAN be precisely regulated to as low as 0.8V, with a maximum tolerance of 0.5% over temperature and line voltage variations.
The ISL6522A provides simple, single feedback loop, voltage-mode control with fast transient response. It includes a 200kHz free-running triangle-wave Oscillator that is adjustable from below 50kHz to over 1MHz. The error Amplifier features a 15MHz gain-bandwidth product and 6V/s slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0100%.
The ISL6522A protects against overcurrent conditions by inhibiting PWM operation. The ISL6522A monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor.
