48V Inverse Buck LED Driver



Inverse buck circuits are ideal for driving high brightness LEDs with
high efficiency. This example drives two ~11V Lumileds LEDs at around
700mA with 48V DC input. The selected 60V OptiMOS™ MOSFET
is perfect thanks to its low cost, low gate charge.
This power stage can be found on the RGB LED Lighting Shield with
XMC1202 for Arduino.
