The RT8127A is a high efficiency Dual-Channel output synchronous Buck PWM controller with integrated MOSFET drivers and two LDOs.

This part

® RT8127A High Efficiency Dual-Channel Output Synchronous Buck PWM Controller with Phase Interleaving and Two LDO Regulators.

Green Voltage Mode (GVMTM) control, which is specifically designed to improve efficiency at light load condition. At light load condition, the RT8127A 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 RT8127A leaves the diode emulation mode and operates in Continuous Conduction Mode (CCM) with fixed-frequency, 180° out of phase interleaved PWM to r.
