LM3553: 0.5ms ON time, about 5.56ms period possible?

Part Number: LM3553

Hi team,

Customer want to use LM3553 with the following specification.

VIN = 3.3V

LED : Vf=1.5V – 2.1V,  If = about 400mA, 2-parallel×5-sleaze

ON time = 0.5ms, period = 5.56ms, synchronizing 2-parallel,

Is this possible with LM3553?

  • Hi Yoshwa,
    I'm not sure whether Lm3553 can support this short pulse, but I will try to apply an EVM to evaluate this. You can also apply an EVM to have a try. thanks.
