Overview

The RK860 is a high efficiency 2.4MHz synchronous step down DC/DC regulator IC capable of delivering up to 6A output current. It can operate over a wide input voltage range from 2.7V to 5.5V. And, it integrates a main switch and a synchronous switch with both very low RDS (ON) to minimize the conduction loss. The output voltage can be programmed from 0.7125V to 1.5V with 12.5mV/step or 0. 5V to 1.5V with 6.25mV/step through I²C interface. The RK860 is in a space saving, low profile WLCSP 1.65mm*2.05mm-20 package.
