LED LED DRIVING APPARATUS FOR IMPROVING COMMON IMPEDANCE EFFECT

摘要

The present specification discloses an LED driving apparatus in which a voltage drop due to a common impedance is improved. The LED driving apparatus according to the present specification configures a circuit by combining NMOS or PMOS so that a positive power source or negative power source is not connected to a source terminal of a MOSFET. Accordingly, a common impedance effect in the positive power source or negative power source may be removed.
