BP5132HC is a high-precision linear triac LED control chip that integrates a high-voltage rectifier tube and JFET high-voltage power supply function. It is mainly used to drive high-voltage and low-current LED string powered by 120Vac. Since no magnetic elements are required, the LED driver can achieve small size, long life, and comply with EMI regulations. BP5132HC can accurately set the LED current through an external resistor. BP5132HC has an over-temperature adjustment function. When the input voltage is too high or the LED current is too large, this function will reduce the output current.
