EPC EPC23108 & EPC23109 100V 35A ePower™ Stage ICs

Efficient Power Conversion (EPC) EPC23108 and EPC23109 100V 35A ePower™ Stage Integrated Circuits (ICs) feature integrated high-side and low-side eGaN® FETs with an internal gate driver and level shifter. These ICs offer 35A continuous power-stage load current, 100V absolute maximum input voltage, and 5V nominal bias supply voltage in a 3.5mm x 5mm package. The thermally enhanced QFN package has an exposed top for low thermal resistance from the junction to the top-side heatsink. The EPC23108 and EPC23109 series are both designed using EPC's proprietary GaN® IC technology. The result is a power-stage IC that translates logic-level control signals into a high-voltage and high-current power stage, which is more efficient to operate while being smaller in size, simpler to design, and easier to manufacture.

Features

  • Integrated high-side and low-side eGaN FET with internal gate driver and level shifter
  • Independent high-side and low-side control inputs
  • Logic lockout commands both FETs off when inputs are both high at same time
  • External resistors to tune SW switching times
  • Robust level shifter operation for hard and soft switching conditions
  • Synchronous charging for high-side bootstrap supplies
  • Standby function for low quiescent current mode
  • Fast PWM shutdown when (SD/STB) pulled low
  • Power-on-reset for low-side and high-side power supplies
  • Power stage high impedance guaranteed in absence of VDRV/VBOOT supplies
  • 0% and 100% duty capable
