BP3339 High PF PSR LED Driver Controller General Description BP3339 is a high PF PSR constant current LED driver with high current accuracy.
It is suitable for 90Vac-277Vac universal input.
BP3339 realizes high PF by constant on time control.
With internal THD optimizer, the THD of input current can be lower than 15% under universal input.
BP3339 works in BCM mode, which can help to improve switching loss and EMI performance.
With internal HV start up and fast start up control, BP3339 can build up output current within 500ms.
With internal line and load compensation, BP3339 can achieve excellent line and load regulation.
BP3339 can work as floating buck-boost with single-winding inductor ...
