High Line to 15V to 24V Constant Current Source @ 200mA for High Brightness LED Reference Design
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 LEDsVery small solution (31mm x 38.3mm): suitable for several applicationsNon-isolated constant current source with over-voltage protectionShort circuit protection
