Current Mode PWM Controller 0.6V to 5.5V 100mA 32Pin TQFN EP T/R
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.
