BP5131D datasheet price


The BP5131D is designed for linear driving LED strings with high forward voltage low LED current in line condition.

The BP5131 is a high current precision Linear LED Driver,integrated with High Voltage regulation switchers and JFET supply, specially designed for AC line LED strings forwarded with high voltage and low current.

In application, it supports a quite small BOM benefit from no ECAP and no Magnetics, compile with EMI and safety standard.
