ISL8112
ISL8112 is Main Power Supply Controllers manufactured by Renesas.
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). This device also features a linear regulator providing 3.3V/5V, or adjustable from 0.7V to 4.5V via LDOREF. The linear regulator provides up to 100m A output current with automatic linear-regulator...
