GENERAL DESCRIPTION
OB339F is a primary side regulation off-line LED
lighting controller which can achieve accurate LED
current. It significantly simplifies LED lighting
system design by eliminating the secondary side
feedback circuitry. Proprietary Constant Voltage
(CV) and Constant Current (CC) control is
integrated as shown in the figure below.
The LED current (CC control) can be adjusted
externally by the resistor Rs at SOURCE pin.
OB339F offers comprehensive protection
coverage with auto-recovery features including
Cycle-by-Cycle current limiting, VDD OVP, VDD
clamp and UVLO. Excellent EMI performance is
achieved with On-Bright proprietary frequency
shuffling technique.
OB339F is offered in DIP8 package.
