BP2836 Datasheet – Non-isolated Buck Offline LED Driver IC
BP2836 overview
The BP2836 is a Non-isolated Buck Offline LED Driver made by BPS Confidential, supplied in a DIP 8 Pin Type package. The absolute maximum ratings table on this page lists the 9 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the BP2836 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The BP2836D is a high precision buck constant current LED driver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.
The BP2836D integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low. So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.
The BP2836D utilizes patent pending current control method. It can achieve precise output current and excellent line regulation. The driver operates in critical conduction mode, the output current does not change with the inductance and LED output voltage. The BP2836D offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC under voltage protection, CS resistor short circuit protection and thermal regulation function.
