Fault disconnect switch
Input voltage for the device and LED power
The device needs 4ms for initial power-up Enable. It will be disabled if it is not biased for longer
than 28ms.
De-couple capacitor for internally generated supply rail.
PWM brightness control pin.
/Flag = 0 for any fault conditions. /Flag =1 for normal condition. Open drain that needs pull up.
No Connect
Boost switching frequency set pin by connecting a resistor. See “Switching Frequency” on page 10
