ISL6232
Data Sheet April 18, 2005 FN9116.0
High Efficiency System Power Supply Controller for Notebook Computers
The ISL6232 is a high efficiency, quad output controller optimized for converting battery, wall adapter or network DC input voltage into system supply voltages required for portable applications. The ISL6232 includes two PWM controllers generating 0.8V to 5.5V, or fixed 5V and 3.3V outputs. It also features 5V and 3.3V always linear regulators with up to 100mA output current. ISL6232 uses constant frequency current mode PWM control with out of phase operation for reducing the input ripple current and the ESR requirement of the input capacitors. Over 95% efficiency is achieved through synchronous rectification and dual PWM/Skip mode architecture.
