BP1386 is a buck-type LED constant current controller with hysteresis control that can be deeply dimmed. It is particularly suitable for LED constant current applications such as 0-10V dimming and PWM dimming with a DC input of less than 80V. The PWM pin of BP1386 can accept PWM dimming signals for analog-digital hybrid dimming. When the PWM duty cycle is greater than 10%, analog dimming is used and the output current changes continuously.
