Based on ESP32, HC-SR04 ultrasonic sensor
100 W 2-Stage Boost and Isolated Flyback 3-Way Dimmable LED Ballast using HiperPFS-4 (PFS7626C) and LYTSwitch-6 (LYT6079C, incorporates PowiGaN Technology)
This is a 15W 5V USB adapter reference design board using quasi-resonant PWM IC ICE2QS03G (DSO-8) with CoolMOS™ IPS65R1K5CE (IPAK SL) and secondary side synchronous rectification with OptiMOS™ BSZ100N06LS3G (S3O8, 3x3 mm style SuperSO8) IR1161 (5-pin SOT-23). Designed for high-reliability systems, this reference USB adapter board features a compact form factor, high efficiency, low standby power, various protection methods, and passes conductive electromagnetic interference, ESD, and lightning shock wave testing. Customers only need to make slight changes to this board, and it can be used for production after final confirmation.
