Is there a LED driver design for the following application:

24W Led Driver driving 3 LED strings each having 7 leds in series.

Vin - 80V to 300V AC for rural conditions.

Vout - 24V DC with overvoltage protection,undervoltage protection and short circuit protection

    Hello,

    Since high-reliability is one of the most important  requirements for street lighting, here are two approaches for rural conditions:

    1. No ripple control requirement, single-stage: TPS92314
    2. Low output current ripple two-stage: UCC28810+TPS92511

    For more design information, please visit www.ti.com.

    Thanks.
