24V Inverse Buck LED Driver

Inverse buck circuits are ideal for driving high brightness LEDs with
high efficiency. This example drives a ~11V Lumileds LED at around
700mA with 24V DC input. The selected 30V OptiMOS™ MOSFET
is perfect thanks to its low cost, low gate charge.
This power stage can be found on the LED Current Control Explorer.
