BP2865E is a high-precision step-down LED constant current driver IC. The chip works in the critical continuous mode of inductor current, which is suitable for 85Vac~265Vac full range input voltage non-isolated step-down type LED constant current power supply. The BP2865E chip integrates a 500V power switch with a patent The driving and current detection method of the chip, the working current of the chip is extremely low, No need for auxiliary winding detection and power supply, only a few peripheral elements are needed Parts, you can achieve excellent constant current characteristics, which greatly saves the system System cost and volume. The BP2865E chip has a high-precision current sampling circuit, and at the same time Using patented constant current control technology to achieve high-precision LED Constant current output and excellent line voltage regulation rate. The chip works on electricity Inductive current critical mode, the output current does not vary with the inductance and LED work The operating voltage changes to achieve excellent load regulation. BP2865E has multiple protection functions, including LED open/short Protection, CS resistance short circuit protection, undervoltage protection, chip temperature over Thermal regulation, etc.

Note 1: The maximum limit value means that the chip may be damaged if it exceeds the working range. The recommended operating range means that within this range, the device functions normally, but it is not fully guaranteed. Proof to meet individual performance indicators. The electrical parameters define the specifications of the DC and AC parameters of the device within the working range and under test conditions that guarantee specific performance indicators. Fan. For parameters with no upper and lower limits, the specification does not guarantee their accuracy, but their typical values reasonably reflect the performance of the device.
Note 2: The maximum power consumption will definitely decrease when the temperature rises, which is also determined by TJMAX, θJA, and ambient temperature TA. The maximum allowable power consumption is PDMAX = (TJMAX-TA)/ θJA Or the lower value among the numbers given in the limit range.
Note 3: Human body model, a 100pF capacitor is discharged through a 1.5KΩ resistor.
