    LM3429: LED driver make a lot of noise on FM-radio

    Hi, everyone! I've made a LED buck-boost (BB) driver based on LM3429. It's for automotive lighting, so Vin = 9-14.5 V, LED string consist of 10 white leds. V_out is about 30V, I_out=1.3A. All components were calculated according to LM3429 datasheet for BB topology. All datasheet recommendations...

    How we select LC filter for MAX3221?

    I have seen a schematic where they used MAX3221, RS232 Driver and Receiver. There they have used LC filter of inductor value 0.68uH and capacitor value of 680pF, but in datasheet they have not mentioned about frequency. Can anyone explain how they selected this value?
