AN405
Design Example of CS1680
for 10W Dimmer-Compatible SSL Circuit
Features
• Constant-current Output
• Flicker-free Dimming
• Line Voltage: 12 VAC/VDC, +/- 10%
• Rated Input Power: 10W
• Rated Output Power: 7.8W
• Efficiency: ~82% at 430mA for 6xLEDs in Series

General Description
This application note provides an example of a Solid State
Lighting (SSL) LED lamp circuit designed using Cirrus
Logic’s CS1680, the CRD1680-10W-18V. The CRD1680-
10W-18V reference design demonstrates the performance
of the CS1680 dimmable LED driver for low-voltage lighting
with a 430mA output driving 6xLEDs in series. It provides
exceptional single-lamp and multi-lamp transformer
compatibility for non-dimmer systems and dimmer systems
paired with electronic and magnetic low-voltage
transformers. The form factor is targeted to fit into MR16
LED lamp applications.
