OB3613NCP
OB3613NCP is High PF Non-Isolated Buck LED Lighting Power Switch manufactured by On-Bright.
- Part of the OB3613MCP-On comparator family.
- Part of the OB3613MCP-On comparator family.
DESCRIPTION
OB3613x is a high power factor, highly integrated buck regulator with advanced features to provide high efficiency control and high precision constant current output for LED lighting applications.
OB3613x integrates a MOSFET to decrease physical volume. The proprietary CC control scheme is used and the system can achieve high power factor with constant on-time control scheme.
OB3613x offers prehensive protection coverage with auto-recovery features including LED open loop protection, LED short circuit protection, cycle-by-cycle current limiting, built-in leading edge blanking, VDD under voltage lockout (UVLO), etc.
OB3613x is offered in SOP8, SOP7 or DIP8 package.
