ISL62386
High-Efficiency, Quad Output System Power Supply Controller for Notebook Computers
FN6831 Rev 0.00 February 4, 2009
The ISL62386 controller generates supply voltages for battery-powered systems. The ISL62386 includes two pulse-width modulation (PWM) controllers, adjustable from 0.6V to 5.5V, and two linear regulators, LDO5 and LDO3, that generate a fixed 5V output and a fixed 3.3V output respectively. Each can deliver up to 100mA. The Channel 2 switching regulator will automatically take over the LDO5 load when programmed to 5V output. This provides a large power saving and boosts efficiency.
