Advanced PWM and Linear Power Controller for Portable Applications
The ISL6226 provides power control and protection for two user selected output voltages required in high-performance notebook PC applications. The IC integrates a fixed, selectable frequency pulse-width-modulation (PWM) controller and a 3A LDO linear regulator controller with monitoring and protection circuitry in a single 24 lead SSOP package. The PWM controller regulates the battery input voltage to a user selected output voltage. Synchronous converter and hysteretic operation at light loads contribute to a high efficiency over a wide range of input voltage and load variation....
