[size=21.2667px]Description
The ZCC3820KC is a high-efficiency
step-down LED driver controller with a wide
input voltage range of 7V to 100V.
The ZCC7820KC employs a constant
off-time mode architecture that accurately
regulates LED current with a feedback
coming from an external current-sense
resistor. This control scheme optimizes circuit
stabilization and fast response time without
loop compensation. Its low 280mV average
feedback voltage reduces power loss and
improves the converter’s efficiency.
The ZCC7820KC implements PWM and
analog dimming together through the DIM
pin.
The ZCC7820KC also Includes thermal
overload protection in case of output
overload.
