Cxle8696 has a built-in high precision error amplifier. External MOS boost type high efficiency, stable and reliable high brightness LED driving control IC, built-in high-precision comparator

Cxle8696 has a built-in high precision error amplifier. External MOS boost type high efficiency, stable and reliable high brightness LED driving control IC, built-in high-precision comparator, off-time control circuit, constant current drive control circuit, etc., especially suitable for high-power, multiple high brightness LED lamp strings constant current drive. The fixed off time control mode can work at a frequency of up to 1MHz, which can reduce the external inductance and filter capacitance, reduce the volume and improve the efficiency. Add PWM signal at dim pin to adjust the brightness of LED lamp. By adjusting the external resistance, the driving current of the high brightness LED lamp can be controlled to make the brightness of the LED lamp reach the expected constant brightness. The current flowing through the high brightness LED lamp can vary from several Ma to 2 A
