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 ISL9440B and ISL9440C offer programmable soft-start, independent enable inputs for ease of supply rail sequencing, and integrated UV/OV/OC/OT protecti
