One-Channel High Power LED Controller with DC-DC Converter

for Large LCD Panes

SOP-16L (Top View)

Figure 1, Pin Assignments of OCP8121

◼ 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 in SOP-16L package,

and it is RoHS compliant and 100% lead Pb free.

Operating temperature range of the OCP8121 is from

-40°C to 85°C.
