DESCRIPTION
Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized. It can precisely control the LED current without secondary side sense and feedback circuits. The device integrates a 650V power MOSFET to further reduce external components, for saving cost and PCB area. The BP3316D utilizes patented line and load voltage compensation method to achieve excellent line and load regulation. The BP3316D offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC over voltage protection, VCC under voltage protection, CS resistor open protection and cycle by cycle current limit. All the protection functions are auto-recovery. The system reliability is further improved by the thermal regulation function. The output current is reduced when the driver is over temperature.
