摘要: A load drive device capable of expanding a range an output power by improving linearity thereof when the varies. This includes circuit ( 14 ) for supplying electric to LED 10 ), feedback 28 turning on or off supplied according duty ratio burst signal control and generating value controlling based A/D-converted obtained detecting current (Iout) send out supply is in on-state, previous correcting 64 presently generated (y) (V) (x) which are every cycle signal, determination 66 allowing operate upon determining that goes above below reference value.
