DATASHEETFOR NEW DESIGNS, INTERSIL RECOMMENDS DROP-IN ENHANCED PRODUCT - ISL6535
ISL6522
Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller
FN9030 Rev 8.00 Mar 10, 2006
The ISL6522 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 ISL6522 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 1% over temperature and line
voltage variations.
The ISL6522 provides simple, single feedback loop,
voltagemode 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 enabl...
