Product Summary
The ISL65426HRZ is a high efficiency dual output monolithic synchronous buck converter operating over an input voltage range of 2.375V 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. The ISL65426HRZ switches at a fixed frequency of 1MHz and utilizes current-mode control with integrated compensation to minimize the size and number of external components and provide excellent transient response. The internal synchronous power switches of ISL65426HRZ are optimized for good thermal performance, high efficiency, and eliminate the need for an external Schottky diode.
