DIO8215B

Adaptive 100/120Hz Current Ripple Remover

Max LED Current ≤500mA

Features

Descriptions



Wide input voltage range

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.

Internal 150V power MOSFET

Built-in zener diode for input voltage

clamping



VG output voltage high to 10V

Programmable amplitude of 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.



Multiple protection features:



Reliable LED voltage limit

Reliable LED current limit

Reliable Short LED Protection (SLP)

Hot-plug protection

DIO8215B allows to regulate the cathode voltage

limit of LED string, which could help limit the

power dissipation on chip.

Over Temperature Protection (OTP)

EP-SOIC8 Package

DIO8215B provides over thermal protection.

When the OTP is trigged, the function of current

ripple removing is shielded and MOSFET is ON.

Applications



Flickerless LED lighting
