onsemi

Download the DN05022D datasheet PDF. This datasheet also covers the DN05022 variant, as both devices belong to the same low-cost led dimming family and are provided as variant models within a single manufacturer datasheet.

General Description

This 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.

Key Features

PF = 0.8.
THD = 53.8%.

DN05022/D Low-Cost LED Dimming with Output Capacitor http://onsemi.com DESIGN NOTE Table 1. DEVICE DETAILS Device NSIC2050B, NSI50010Y Application AC LED, Dimmable Input Voltage 100−127 Vac Topology Bridge + CCR and PWM Sensing I/O Isolation No Circuit Description This 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.
