General Description

The OCP8122 is dual channel LED driver controller IC which loads the boost DC-DC controller and the constant current control of LED driver designed to build LED backlight for 3D LCD display mode large-size LCD TV application.

The OCP8122 provides two independently controlled LED drivers to achieve optimum efficiency.

The drive outputs are phase-shifted by 180 degree to minimize current ripple in high power applications.
