LM3630A: PWM duty cycle limitation

Toshiro Imi

Part Number: LM3630A

Hello,

Our customer asked about PWM input duty cycle limitation. Would you let us know PWM minimum duty cycle and maximum duty cycle.

Best regards,

Hi Sir,

A minimum 2% PWM input duty cycle is recommended. Input duty cycles of 1% or less causes delayed off-to-on transitions.

Hello,

Thank you for your reply. We knew about minimum duty. How about maximum duty.

Hi Sir,

Maximum duty cycle should be 100%.
