Other Parts Discussed in Thread: LM3409
According to LM3409 datasheet, we used standard circuit , our application is input voltage is 12V, the output LED lighting is 6V, the current is 1A, the Roff=8K, the Coff=470pF, L=100uH, Rsns=0.2, the EN pin signal is PWM , this PWM frequency is 1K , the LED can be dimming， but when the current is smaller blew 1mA, this LED lighting will be shake， please give us some advice how to improve it .
