Introduction

AI Translation

The RT8115C is a high efficiency single phase synchronous Buck DC/DC controller with 5V/12V supply voltage. The IC features Green Voltage Mode (GVMTM) control, which is specifically designed to improve converter efficiency at light load condition. At light load condition, the IC automatically operates in the diode emulation mode with constant on-time PFM to reduce switching frequency so as to improve conversion efficiency. As the load current increases, the RT8115C leaves the Diode Emulation Mode (DEM) and operates in the continuous conduction mode with fixed frequency PWM. The RT8115C has embedded MOSFET gate driver with high driving capability, supporting driving voltage up to 12V for high output current application. This device uses lossless low-side MOSFET RDS(ON) current sense technique for over-current protection with adjustable threshold set by the LGATE pin (LGOCS). Other features include power good indication, enable/disable control and internal soft-start. The RT8115C also provides fault protection functions to protect the power stage output. With above functions, the IC provides customers a costeffective solution for high efficiency power conversion. The RT8115C is available in the WDFN-10L 3x3 package.
