1 / 2 page  Page1 - 2 Rev. 1.2 Feb .27, 2018 OCP8121 源于灿瑞 磁传天下 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. ◼ Features ⚫ Wide Supply Voltage Range: 8.0V ~ 25V ⚫ One DC-DC Controller ⚫ Number of LEDs in series limited by external MOSFETs rating ⚫ PWM dimming control ⚫ Analog Dimming ⚫ Constant Operation Frequency ⚫ External Power MOSFET Over-Current Protection ⚫ External enable control ⚫ Integrated high frequency oscillator ⚫ Over-voltage protection ⚫ Output to Return Short-circuit Protection ⚫ Output to Ground Short-circuit Protection ⚫ Output Over-Load Protection ⚫ Limited Current Condition Protection ⚫ Low in-rush current soft-start function ⚫ Under-voltage lock-out ⚫ Thermal shutdown ⚫ Fault Status Output ⚫ Low Standby current ⚫ TA= -40 ~ 85 ℃ ⚫ Available in SOP-16L Package ◼ Applications ⚫ LCD White LED Backlighting ⚫ LCD TVs ⚫ Automotive and Infotainment Displays ⚫ 3D Mode Display LCD Panel ◼ Pin Configuration |
