ISL8120IR Dual/n-Phase Buck PWM Controller

DATASHEET ISL8120IR Dual/n-Phase Buck PWM Controller with Integrated Driver FN6763 Rev.2.00 November 11, 2011 The ISL8120IRZEC integrates two voltage-mode synchronous buck PWM controllers to control a dual independent voltage regulator or a 2-phase single output regulator. It has PLL circuits and can output a phase-shiftprogrammable clock signal for the system to be expanded to 3-, 4-, 6-, 12- phases with desired interleaving phase shift. It also integrates current sharing control for the pow.

ISL8120IR Features

* enhance the value of ISL8120IRZEC. The ISL8120IRZEC protects against overcurrent conditions by inhibiting the PWM operation while monitoring the current with rDS(ON) of the lower MOSFET, DCR of the output inductor, or a precision resistor. It also has a PRE-POR Overvoltage Protection option, which p
