OCP8121

WWW.ORIENT-CHIP.COM OCP8121 One-Channel High Power LED Controller with DC-DC Converter for Large LCD Panes ◼ General Description The OCP8121 is single 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 OCP8121 provides one controlled LED drivers to achieve optimum efficiency. The OCP8121 provides PWM dimming function and analog dimming control. It provides system design flexibility for LCD-TV with local dimming or 3D display mode. The OCP8121 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 OCP8121 is available...
