CL88020 DEVICE OVERVIEW

The CL88020 LED driver integrated circuit (IC) is targeted at general LED lighting

products, such as A19 bulb with a maximum power rating of about 8.5W at 120 VAC

(60W incandescent equivalent bulbs).

CL88020 DEVICE KEY FEATURES

• Monolithic

- No external FETs, minimum driver component count

• No inductors

- Reduces BOM cost and circuit complexity

• Efficient operation

- Typical electrical efficiencies of 80% to 83% across the AC input voltage

range.

• No high frequencies

- Inherently low conducted EMI, no need for input filters

• Inherently dimmer compatible

- Works with most leading-edge and trailing-edge phase-cut dimmers

- TRIAC dimmer compatible

• 120 VAC only

- Reduces die size by optimizing output FET voltages and sizes

• Targeted for 8.5W output

- 60W incandescent equivalent (most popular), assuming minimum 94 Lm/W

efficacy

•4 taps

- Fewer pins reduces footprint size
