BP5926X is a high-performance stepless color adjustment control chip with a built-in dual-channel MOSFET. By adjusting the duty cycle of the input PWM signal, the luminous proportions of the two channels of LED light sources are adjusted to achieve the purpose of color adjustment. The output currents of the two channels of LEDs are complementary. During the color adjustment process, the total current remains unchanged and is equal to the current of the constant current source. BP5926X can be compatible with PWM signals with amplitudes of 33V/5V. The withstand voltage from the floating high-voltage side to GND can reach 600V, and it can be widely adapted to various LED constant current drive circuits.
