 Note: DOZ嘉泰姆
1. Keep feedback wiring away from inductor and schottky.DOZ嘉泰姆
2. VIN, SW, LED+, LED- lines must be short and ground plane construction for best results.DOZ嘉泰姆
3. C3,R1,R2 and R3 are used for the designing with PWM dimming. If not with PWM dimming, R1 replaced DOZ嘉泰姆
with 0 ohm, C3,R2,R3 open.
