OCP8122SSAD规格书详情
◼ 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.
