The NDP3820KC is a high-efficiency step-down LED driver controller with a wide input voltage range of 7V to 100V.
The NDP3820KC 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 NDP3820KC implements PWM and analog dimming together through the DIM pin.
The NDP3820KC also Includes thermal overload protection in case of output overload.
