Figure 2. PWM operation at various duty cycles; note that there is no startup delay during PWM dimming operation

• Operating conditions: at 200 Hz, VIN = 24 V, VOUT = 15 V, R1 = 63.4 kΩ, duty cycle = 50% (panel 2A) and 2% (panel 2B)

• CH1 (Red) = VIN (10 V/div), CH2 (Blue) = VOUT (10 V/div),

CH3 (Green) = iLED (500 mA/div), CH4 (Yellow) = Enable (5 V/div), time scale = 1 ms/div (panel 2A) and 50 μs/div (panel 2B)

Panel 2A. Duty cycle = 50% and time scale = 1 ms/div

Panel 2B. Duty cycle = 2% and time scale = 50 μs/div
