Cxle8298 is a high efficiency, stable and reliable high brightness LED lamp driving control IC, with built-in high-precision comparator, off-time control circuit, constant current driving control circuit, etc., especially suitable for high-power, multiple high brightness LED lamp strings constant current driving.
Cxle8298 adopts fixed off time control mode, its working frequency can be as high as 2.5MHz, which can reduce external inductance and filter capacitance, reduce volume and improve efficiency. Add PWM signal at en end to adjust the brightness of LED lamp. By adjusting the external resistance, the driving current of the high brightness LED lamp can be controlled so that the brightness of the LED lamp can reach the expected constant brightness. The current flowing through the high brightness LED lamp can vary from a few Ma to a ampere
