OC5120BA is a high-efficiency, high-precision switching step-down high-power LED constant current driver IC with built-in 100V power MOS.
OC5120BA OPERATES IN A FIXED-FREQUENCY PWM MODE WITH A TYPICAL OPERATING FREQUENCY OF 140KHZ.
OC5120BA Uses an average current detection mode and therefore has excellent load regulation characteristics.
OC5120BA The high and low brightness function is integrated, and the high and low brightness functions can be switched through the HL port. HI is in high brightness mode, and H is connected to low light mode with high level of 1/2 current.
OC5120BA The VDD regulator and over-temperature protection circuits are also integrated to reduce the number of external components and improve system reliability.
OC5120BA is available in an ESOP8 package. The heatsink has a built-in SW pin.
