The EPC23103ENGRT from Efficient Power Conversion is an ePower Stage Power Management IC that is ideal for buck converters, boost converters, buck-boost converters, half-bridge, full-bridge LLC converters, motor drive inverters, and Class D audio amplifier applications. It requires an input voltage of up to 100 V and a nominal bias supply voltage of 5 V. This PMIC consists of an integrated high-side and low-side eGaN FET with an internal gate driver, a level shifter, bootstrap charging, and gate drive buffer circuits, 3.3 V or 5 V CMOS input logic levels, independent high-side and low-side control inputs, and external resistors to tune SW switching times and over-voltage spikes above the rail and below ground. It offers synchronous charging for high-side bootstrap supply, false trigger immunity from fast switching transients, robust level shifting functionality to operate for hard and soft switching conditions, and logic lockout commands to switch OFF both the FETs when inputs are both high at the same time.

This eGaN PMIC translates logic level input to high voltage and high current power output that is smaller in size, easier to manufacture, simpler to design, and more efficient to operate. It offers power-on reset functionality for low-side VDD and high-side VBOOT supply. This PMIC activates gate pull-down functionality for high side (HS) FET and low side (LS) FET with the loss of VDRV supply. It is available in a thermally enhanced surface-mount package that measures 3.5 x 5 mm.
