◼ General Description

The OCP8122A 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 OCP8122A 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. The

OCP8122A provides independent PWM dimming

function for each channel and common analog dimming

control for both channels. It provides system design

flexibility for LCD-TV with local dimming or 3D display

mode.

The OCP8122A can be configured for Master-Slave

operation to support multi-channel applications.

Synchronization is achieved by a proprietary single-wire

interface which minimizes system components.

The OCP8122A provides the over-voltage

protection (OVP), Power MOSFET over-current

protection (OCP), Output to ground short-circuit

protection, output over load protection, Soft-Start (SS),

under-voltage lock-out (UVLO), limited current condition

(LCC) protection, thermal shutdown protection (TSD). A

soft-start feature is provided to minimize in-rush current

during start-up.

The OCP8122A is available in SSOP-24L and

SOP-24L package, and it is RoHS compliant and 100

lead Pb-free. Operating temperature range of the

OCP8122A is from -40°C to 85°C.
