Efficient Power Conversion (EPC) expanded its family of footprint-compatible ePower Stage ICs to boost power density and simplify design for power requirements in DC-DC apps, motor drives, and class-d audio amplifiers. The company introduced two new 100 V power stage ICs rated at 15 A (EPC23104) and 25 A (EPC23103). The two devices join the 100 V 35 A power stage IC EPC23102 currently offered by EPC.
The three ICs are capable of a maximum withstand voltage of 100 V and integrate a complete GaN half-bridge power stage, including symmetrical FETs in half-bridge configuration, half-bridge driver, level shifter, bootstrap charging, and input logic interface.
They feature a thermally enhanced QFN package measuring only 3.5 mm x 5 mm with exposed top for dual side cooling and wettable flanks. Customers can upgrade their design without modification to the board and, therefore, can easily adapt to changing load requirements.
In DC-DC applications, the devices can operate with high efficiency at high switching frequency and offer higher performance and smaller solution size for 28 V – 60 V DC-DC in computing, industrial, and USB PD 3.1 applications. In 32 V – 48 V BLDC motor drives for e-mobility, robotics, power tools, and drones. Devices operate with small deadtimes and at 100 kHz to increase the system efficiency due to less motor core losses and vibrations and to reduce or eliminate the electrolytic capacitors.
The development board, EPC90151, and EPC90152 are half-bridge demo boards featuring the EPC23103 and the EPC23104 ePower Stage ICs. The boards simplify the evaluation process of the EPC23103 and the EPC23104. The 2” x 2” boards are designed for optimal switching performance and contain all critical components for easy evaluation. EPC23103 is priced at $3.75 each in 1 Ku volumes. The EPC23104 priced at $3.00 each in 1 Ku volumes. Development boards EPC90151 and EPC90152, are priced at $200.00 each.
Designers interested in replacing their silicon MOSFETs with a GaN solution can use the EPC GaN Power Bench’s cross-reference tool to find a suggested replacement based on their unique operating conditions.
