OB3613x Series
High PF Non-Isolated Buck LED Lighting Power Switch
GENERAL 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 comprehensive 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.

Note: Maximum practical continuous power in an open frame design with sufficient drain pattern as a heat sink, at 50℃ ambient
and 60℃ temperature rise. Higher output power is possible with extra added heat sink、air circulation and decrease output current to
reduce thermal resistance.
