: Schematic diagrams for specific television models from brands like Hisense or Crown often include the implementation details of the SN51DP within the power or scaler board sections.
The SN51DP is a SOP-10 package IC designed for driving constant current to LED arrays. SOP-10 (Small Outline Package with 10 pins). Operating Voltage: Typically operates on a 12V supply rail.
If the SN51DP is obsolete (many "SN" prefix parts are), the datasheet allows you to cross-reference.

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.

In repair scenarios, technicians sometimes bypass the protection circuit by connecting a resistor from Pin 9 (OVP) to diagnose backlight issues. Equivalency:
The commonly found in LCD/LED television power management setups. Manufactured primarily in standard SSOP-10 / MSOP-10 packages , this component controls the power delivery, brightness modulation, and system protection circuits for backlighting arrays in flat-screen TVs and monitors. When troubleshooting display issues like a blank screen with sound, repair technicians frequently look for the SN51DP datasheet PDF to evaluate its pin configurations and protection limits.
package), but the actual part number might be different (e.g., TLV series). Third-Party Repositories Operating Voltage: Typically operates on a 12V supply rail
Many searches for the "sn51dp datasheet pdf" come from people repairing old electronics. Unlike a standard 7805 voltage regulator, the SN51DP is more niche. The datasheet is the only reliable source to confirm pinouts and electrical behaviors.
The SN51DP is a backlight management IC. Its primary function is to convert input power to drive the high-voltage LED (Light Emitting Diode) strips that illuminate the screen. You will typically find it in a compact (Shrink Small Outline Package) or TSSOP-10 (Thin Shrink Small Outline Package) housing, which is ideal for space-constrained TV chassis designs. In many circuits, it is also labeled as SN510P , which is essentially an equivalent model.
(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
