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.
