Additional preview pages of the RT8127 datasheet.

The RT8127 is a high efficiency Dual-Channel output synchronous Buck PWM controller with integrated MOSFET drivers and two LDOs.

Green Voltage Mode (GVMTM) control, which is specifically designed to improve efficiency at light load condition. At light load condition, the RT8127 is pin configurable to automatically operate in diode emulation mode with constant on-time PFM to reduce switching frequency so as to improve conversion efficiency. As the load current increases, the RT8127 leaves the diode emulation mode and operates in Continuous Conduction Mode (CCM) with fixed-frequency, 180° out of phase interleaved PWM to red.
