Abstract (en)

[origin: EP2919559A2] A light emitting load driving apparatus includes a first switching element, a second switching element, and a gate driver, to drive first and second light emitting loads connected in series. The first switching element, when in an ON state, bypasses a current to be passed to the first light emitting load. The second switching element, when in an ON state, bypasses a current to be passed to the second light emitting load. The gate driver reduces at least one of an overshoot current caused when the first and second switching elements are simultaneously turned on and an undershoot current caused when the first and second switching elements are simultaneously turned off.
