Dual/n-Phase Buck PWM Controller with Integrated Drivers
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 power module to operate in parallel, which offers high system flexibility.
