DIO8215B

描述

DIO8215B is used to drive a LED string, and remove the 100/120Hz current ripple on AC/DC power by a capacitor between VC and GND. The adaptive technology of DIO8215B ensures minimum power dissipation on DIO8215B while removing LED current ripple. DIO8215B clamps the input voltage on VIN pin by 37V. DIO8215B allows to regulate LED current limit, which protects DIO8215B from being damaged when LED short or hot-plug. DIO8215B allows to regulate the cathode voltage limit of LED string, which could help limit the power dissipation on chip. DIO8215B provides over thermal protection. When the OTP is trigged, the function of current ripple removing is shielded and MOSFET is ON.
