| | Function | Measured/Working Voltage | Notes | | :--- | :--- | :--- | :--- | | 1 | IC Supply / Power Input | 12V | Typical input voltage from the main power supply. | | 2 | Unknown / Ground | 0V | Often found to be at circuit ground potential. | | 4 | Current Protection (OCP) | N/A | If the output current exceeds the set threshold, the IC shuts down to prevent damage. | | 5 | Feedback / Current Sense | 2.5V | The voltage on this pin is used to regulate the LED current. | | 9 | Voltage Protection (OVP) | 1.55V (normal) / 0.8V (fault) | This pin monitors the output voltage. It triggers protection if the voltage is too low or too high (>2V). | | 10 | Enable / On/Off Control | 3.1V | Typically, a high voltage on this pin enables the IC, while a low voltage disables it. |

The SN51DP acts as a specialized driver for backlights (e.g., in monitors or specialized displays).

The SN51DP is not just limited to TVs; its versatility makes it popular in:

The most critical part of verifying any component datasheet is checking its operational limits. For the SN51DP, the following parameters are the most frequently cited across various sources and manufacturer listings, confirming a functional common ground. | | 2 | Unknown / Ground |

Many counterfeit SN51DP modules fail at 400V or over 1.5A. Always purchase from authorized distributors or verify with a curve tracer before mass production.
