EM8800A Constant Off Time, Current-Mode Controller for LED Applications General Description EM8800A is a constant off time current mode controller. This device can operated with a fixed off time of the power switch. The TOFF pin is provided to set the off time. In addition, the PWMD pin enables the user to use a PWM signal to modulate the switching pattern and adjust the average luminosity. The LD/SS pin enables the user to set peak current by adjust the voltage of this pin. This part includes internal soft start, maximum on time protection, over current protection and thermal shutdown function. This part is available in SOP-8 package.
