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.

device. These are stress ratings only, functional operation of
the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not
implied. Exposure to absolute maximum-rated conditions for
extended periods may affect device reliability.
