Light source driving apparatus and light source apparatus having the same |
摘要 |
A light source driving apparatus includes; a boosting part which boosts an input voltage received from an input part and generates a driving voltage, a boosting transistor which controls an operation of the boosting part, a rectification part connected between the boosting part and an output part and which transmits the driving voltage to the output part, an integrated circuit which generates a gate signal which controls the boosting transistor, and a protection circuit which generates a protection signal which controls a voltage level of the gate signal according to an output current of the boosting transistor. |
