EPC Introduces 60W Class-E Amplifier Development Board
Differential mode board uses latest generation 200V eGaN FETs and operates up to 15MHz
Efficient Power Conversion (EPC) has introduced a 60 W Class-E amplifier development board with the company's latest generation 200V eGaN FETs.
The EPC9083 development board has been designed to enable power system designers to evaluate the high efficiency achieved with a high performance 200 V GaN transistor in a class-E amplifier used in wireless power, LiDAR, current-mode class-D, and push-pull converters operating up to 15 MHz.
The GaN-based differential mode development board can operate up to 15 MHz, including 6.78 MHz which is popular for wireless power applications.
Although designed for class-E applications, such as wireless power, the board can be used for any application where a low-side switch is used. Examples include push-pull converters, current-mode class-D amplifiers, common source bi-directional switch, and high voltage narrow pulse width applications such as LiDAR.
The EPC9083 features the EPC2046, EPC's latest generation 200 V, 25 mÎ© eGaN FET. The EPC2046 allows less switching loss than the previous generation of eGaN FETs, in a smaller size, while keeping the same drain-source on-resistance.
The amplifiers are set to operate in differential mode and can be re-configured to operate in single-ended mode and include the gate driver and logic supply regulator.
