The OC5220 is a multi-functional average-current LED constant current driver with simple peripheral circuits for step-down buck high-power dimming constant current LEDs in the voltage range of 5-100V.
The chip PWM port supports ultra-small duty cycle PWM dimming and can respond to a minimum pulse duration of 60ns. When the PWM terminal is high, the chip works normally. When the chip is low, the chip output is turned off.
The chip adopts an average current control algorithm, and the output current constant current accuracy is 3, and the output current is less affected by the input and output voltage and system inductanceThe chip integrates loop compensation, the peripheral circuit is simple, and the system is more stable and reliable.
The chip realizes three-function switching by controlling the LD port. When LD is in the air, the system is in highlight mode;When LD is VDD, the system is in low-brightness mode with 1 2 currentsld followed by 02-1.When the 2V analog dimming signal is input, the system is in analog dimming mode. LD is used to switch between high and low beams for automotive LED lighting. LD simulates the dimming mode when the port voltage is below 02V, the output is off.
