High-Efficiency, Quad or Triple-Output System Power Supply Controller for Notebook Computers

The ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C and ISL62383C family of controllers generate supply voltages for battery-powered systems. These controllers include 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 and an adjustable output respectively, and each can deliver up to 100mA. The ISL62383 and ISL62383C have the same outputs as the ISL62381, ISL62382, ISL62381C and ISL62382C but without LDO3 linear
regulator. The channel 2 switching
regulator will automatically take over the LDO5 load when programmed to 5V output. This provides a large power savings and boosts efficiency. These controllers include onboard power-up sequencing, two power-good (PGOOD) outputs, digital soft-start, and ...
