48V Inverse Buck LED Driver, with totem pole gate driver
VDC IN
LEDs
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 CCM Buck LED Driver with
XMC1402.
