Single Output Mobile-Friendly PWM Controller
FN9042 Rev 8.00 June 8, 2006
The ISL6224 provides power control and protection for a single, adjustable output voltage required to power chip-sets and memory banks in high-performance notebooks and PDAs. This output voltage is adjustable in the range from 0.9-5.5V.
The hysteretic or PWM controller regulates the output voltage from battery voltages ranging from 4V to 24V. Synchronous rectification and hysteretic operation at light loads contribute to a high efficiency over a wide range of input voltages and loads. Efficiency is even further enhanced by using MOSFET’s r DS(ON) as a current sense ponent. Feed-forward ramp modulation, average current mode control and internal feed-back pensation provide fast and firm handling of transients when powering advanced chip sets.
