ISL8112 - Main Power Supply Controllers

Features

  • high light load efficiency which is especially preferred in systems concerned with high efficiency in wide load range, like the battery powered system. ISL8112 includes two constant on-time PWM controllers. Either of the two outputs can operate in output fixed mode or adjustable mode. In fixed mode, one output can be 5V or 3.3V and the other can output 1.5V or 1.05V. In output adjustable mode, one output can be 0.7V to 5.5V, and the other output can range from 0V to 2.5V (sensing output voltage.

DATASHEET ISL8112 High Light-Load Efficiency, Dual-Output, Main Power Supply Controllers FN6396 Rev 1.00 August 10, 2010 ISL8112 is a dual-output Synchronous Buck controller with 2A integrated driver. It features high light load efficiency which is especially preferred in systems concerned with high efficiency in wide load range, like the battery powered system. ISL8112 includes two constant on-time PWM controllers. Either of the two outputs can operate in output fixed mode or adjustable mode. In fixed mode, one output can be 5V or 3.3V and the other can output 1.5V or 1.05V. In output adjustable mode, one output can be 0.7V to 5.5V, and the other output can range from 0V to 2.5V (sensing output voltage directly) or up to 5V (using resistor divider voltage for voltage sensing).
