Description
- DN05022/D, Design Circuit can be thought of as having two separate portions. There is an LED management portion and a dimmer management/PWM Signal portion. The LED management portion charges the output capacitor to run the LEDs in a DC state. The dimmer management portion provides loading current for the TRIAC in a dimmer and provides a gate voltage to the series-pass MOSFET. The gate drive of the series MOSFET PWMs the LEDs at their peak current rating. The NSIC2050B Constant Current Regulators regulate the current through the LEDs. The NSI50010Y limits the power consumption of the dimmer management circuit
