6A Dual Synchronous Buck Regulator with Integrated MOSFETs

The ISL65426 is a high efficiency dual output monolithic synchronous buck converter operating over an input voltage range of 3V to 5.5V. This single chip power solution provides two output voltages, which are selectable or externally adjustable from 1V to 80 of the supply voltage while delivering up to 6A of total output current. The two PWMs are synchronized 180° out-of-phase, reducing the RMS input current and ripple voltage.
