Features
* Three integrated synchronous buck PWM controllers - Internal bootstrap diodes - Internal compensation - Internal soft-start
* Independent control for each regulator and
Applications
* Each output is adjustable down to 0.8V. The PWMs are synchronized at 180° out of phase thus reducing the RMS input current and ripple voltage. The ISL9440, ISL9440A and ISL9441 offer internal soft-start, independent enable inputs for ease of supply rail sequencing, and integrated UV/OV/OC/OT protec
