The OC6780 is a high-efficiency, high-precision step-up LED constant current driver IC with a built-in 100V2A power MOS and can support up to 100V output voltage.
OC6780 has built-in high-precision error amplifier, oscillator, constant current drive circuit, etc., which is especially suitable for high-power, multiple high-brightness LED string constant current drive.
The OC6780 is PWM controlled at a fixed frequency, and the operating frequency can be set with an external resistor
The OC6780 has built-in frequency compensation, eliminating the need for external compensation, simple application design, and fewer external components.
The OC6780 integrates soft-start, output over-voltage protection, cycle-by-cycle current limiting, and over-temperature protection circuitry to reduce external components and improve system reliability.
The OC6780 is available in an ESOP8 package. The heatsink has a built-in SW pin.
