ISL6236, Main Power Supply Controllers

DATASHEET ISL6236 High-Efficiency, Quad-Output, Main Power Supply Controllers for Notebook Computers FN6373 Rev 6.00 April 29, 2010 The ISL6236 dual step-down, switch-mode power-supply (SMPS) controller generates logic-supply voltages in battery-powered systems.

The ISL6236 include two pulse-width modulation (PWM) controllers, 5V/3.3V and 1.5V/1.05V.

The output of SMPS1 can also be adjusted from 0.7V to 5.5V.

The SMPS2 output can be adjusted from 0V to 2.5V by setting REFIN2 voltage.

ISL6236 Features

* a linear regulator providing 3.3V/5V, or adjustable from 0.7V to 4.5V output via LDOREFIN. The linear regulator provides up to 100mA output current with automatic linear-regulator bootstrapping to the BYP input. When in switchover, the LDO output can source up to 200mA. The ISL6236 includes on-board
