The is a specialized power management Integrated Circuit (IC) primarily used as an LED backlight driver in liquid crystal display (LCD) applications. Manufactured by ON-Brig , this component is commonly found in the inverter and scaler boards of LED TVs from brands such as Arielli, Crown, Felix, and Hisense. Technical Specifications & Features
Standalone digital pulse width modulator (DPWM) and LED driver. Operating Voltage: Minimum supply voltage of to a maximum of Temperature Range: Operating temperature from -20°C to +85°C (some sources list up to 130°C). Package Type: 10-pin SSOP/MSOP (Small Outline Package). Resolution: Programmable resolution up to Pin Configuration (Typical 10-Pin Layout) sn51dp datasheet pdf
Based on circuit schematics, the 10-pin MSOP/SSOP configuration is typically defined as follows: Description Input voltage supply Dimming control input Output to drive the external MOSFET Over-Voltage Protection sense System ground Compensation pin for stable operation Current Sense Feedback pin Current set pin (often connected to a resistor) Reference voltage output Practical Maintenance Tip SN51DP The is a specialized power management Integrated
(the "SN" prefix is common for TI parts). However, standard public databases often list these as "marking codes" or "top-side markings" rather than the full part number. Potential Data Sources Operating Voltage: Minimum supply voltage of to a
