High Line to 15V to 24V Constant Current Source @ 200mA for High Brightness LED Reference Design

Overview

TopologyBuck Converter
Input voltage184-270 V
Output 124 V / 0.2 A
IC revisionB

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
