Manufacturer:HD Description:An on-chip PWM dimming circuit enables and disables the current mode regulator for each dimming cycle. It also disconnects the feedback network from the compensation node (VC) to reduce slew time at the next enable time. The oscillator for the dimming PWM produces a triangle wave whose frequency is determined by an external capacitor on the CDIM pin. The dimming PWM frequency is equal to 5Hz/CDIM(µF) with its duty cycle set by the voltage on the |
