Infineon Technologies EVAL_5AR0680AG-1_44W1 Evaluation Board
Infineon Technologies EVAL_5AR0680AG-1_44W1 Evaluation Board is a 44W, 12V evaluation board designed in a fixed-frequency flyback converter topology using the CoolSET™ 5th Generation Fixed-Frequency Plus ICE5AR0680AG-1 switching controller. The ICE5AR0680AG-1 device offers high efficiency, low standby power with selectable entry, an exit standby power option, a wide VCC operating range with fast startup, robust line protection with input overvoltage protection (OVP), and various modes of protection for high-reliability systems.
This Infineon evaluation board is operated in continuous conduction mode (CCM) and runs at a 100kHz fixed switching frequency to optimize low-line full-load efficiency. The frequency reduction with soft gate driving and frequency jittering offers lower EMI and better efficiency between light to 50% load. The selectable Active Burst Mode power enables ultra-low power consumption.
