High Line to 15V to 24V Constant Current Source @ 200mA for High Brightness LED Reference Design
Overview
| Topology | Buck Converter |
| Input voltage | 184-270 V |
| Output 1 | 24 V / 0.2 A |
| IC revision | B |
Description
A high voltage integrated-FET Buck converter is used to supply 200mA constant current to LEDs. The output voltage can range between 15V and 24V. An open-string protection circuit clamps the output voltage to stay always below 34V. The input voltage range is 184AVC to 270VAC
Features
- Simple integrated HV-FET (700V) buck drives up to 8 high-brightness LEDs
- Very small solution (31mm x 38.3mm), suitable for several applications
- Non-isolated constant current source with over-voltage protection
- Short circuit protection
- REMARK: BOM AND SchematiC is added
