EPC EPC23102 100V 35A ePower™ Stage IC
Efficient Power Conversion (EPC) EPC23102 100V 35A ePower™ Stage Integrated Circuit (IC) combines core blocks and eGaN® output FETs into a single monolithic IC. The EPC23102 integrates an input-logic interface, synchronous bootstrap charging, high-side level shifting, and gate drivers. The compact 3.5mm x 5mm QFN package uses EPC's proprietary GaN IC technology. This design results in a power stage IC that translates logic-level control signals into a high-voltage and high-current power stage. Additional features include a 35A power-stage load current (1MHz), 100V absolute maximum input voltage, a 5V external bias supply, and 3.3V or 5V CMOS input logic levels. This ePower stage IC from EPC is designed to be smaller, easier to design and manufacture, and more efficient to operate.
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
- Robust level shifter operation for hard and soft switching conditions
- External resistors to tune SW switching times
- Synchronous charging for high-side bootstrap supply
- Standby function for low quiescent current mode
- Power-on-reset for low-side and high-side power supplies
- Power stage high impedence guaranteed in absence of VDRV/VBOOT supplies
Applications
- Buck, boost, and buck-boost converters
- Half- and full-bridge LLC converters
- Motor drive inverters
- Class D audio amplifiers
