Specification Details Type LED Driver / Power Management IC Package 10-pin SSOP / MSOP Applications LCD TV & Monitor Backlighting, DC Motor Control Max Operating Temp Up to 85°C Compliance RoHS Compliant Pinout Configuration
The in liquid crystal display (LCD) applications. Commonly manufactured by ON-Brig and engineered in a compact 10-pin package (SSOP-10 or MSOP-10), this specialized controller regulates current delivery to LED strips within modern television panels. It is widely found on standard Chinese mainboards (such as the TP.S506.PB801) used by consumer TV brands like Arielli, Crown, and Felix.
Note: There is a separate result showing "SN5-0R1B" as a wirewound resistor by Bourns Electronic Solutions (Riedon Series). However, based on the specific "SN51DP" query, the LCD power chip description is the primary match. To get you the exact details, If you're performing a repair, would you like
The SN51DP is engineered to provide precise control over high-brightness LED arrays. It manages power conversions (typically configured as a boost converter) while handling dimming signals and complex safety loops.

The is a high-efficiency LED backlight driver integrated circuit (IC) manufactured by On-Bright. It is widely used in the power management and inverter boards of liquid crystal display (LCD) and LED televisions, notably in budget-friendly brands like Arielli, Crown, and Felix. Packaged in a compact 10-pin SSOP/MSOP configuration, this chip acts as a standalone pulse-width modulator (PWM) controller engineered to step up supply voltages and precisely regulate current through an external MOSFET.
The IC utilizes a compact 10-pin layout optimized for space-constrained television control boards. Each pin plays a distinct role in monitoring current feedback, regulating operating voltages, or receiving dimming signals from the television’s central processor.
The SN51DP's functionality is defined by its 10 pins. While a complete pinout is not publicly available, crucial functions are well-documented by field technicians:
