ISL65426HRZ-T

6A Dual Synchronous Buck Regulator with Integrated MOSFETs

开关稳压器 W/ANNEAL DL BUCKG

The ISL65426HRZ-T 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.
