Designed for a fast start-up time (typically Industrial Control Systems : The LZC8650C is used

  • Basic constant current LED driver
  • PWM dimming via external signal
  • Analog dimming (using a voltage or variable resistor)
  • Input and output capacitor selection (ESR, voltage rating, temperature stability)

Without proper thermal design, the LZC8650C will enter thermal shutdown or fail prematurely. The datasheet provides: Designed for a fast start-up time (typically

L_min = (Vin_max - Vout) * (Vout / Vin_max) / (Fs * ΔIL)

Short-Circuit Protection (SCP):

Safeguards the circuit in case of an output short.
