BP3212
High Efficiency TRIAC dimmable LED Driver
Description
The BP3212 is a high efficiency TRIAC dimmable
LED driver. The device operates in critical conduction
mode and is suitable for buck, buck-boost or fly-back
LED lighting.
The BP3212 integrates a 300V power MOSFET. It
utilizes patent pending MOSFET driving technique
and current sensing method. The operating current of
the IC is very low. With very few external components
count, it can achieve excellent constant current
performance, so the system cost and size are greatly
reduced.
The BP3212 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.
The BP3212 is available in a SOP8 Package.
