The SN51DP is almost always found in a configuration, driving one or more series‑connected LED strings. Based on analysis of several LED TV power supply boards (e.g., Amoi LE22, Konka LED42E330N), the following key components surround the IC:

| Parameter | Symbol | Typical | Unit | Description | |---|---|---|---|---| | | tr | 20 | ns | Output rise (10% → 90% of VDD) | | Fall Time | tf | 20 | ns | Output fall (90% → 10% of VDD) | | Propagation Delay | tpd | 25 | ns | Input–output signal delay |

The deadtime pin (Pin 4) allows fine-tuning of the non-overlap time. A resistor ( R_DT ) to GND sets the deadtime as: AI Mode history New thread AI Mode history

Given the specialized nature of the part, you may need to directly request the documentation.

The IC is frequently found on TV main boards such as the . It is compatible with various LED TV brands, including Arielli , Crown, and Felix. Design Considerations & Tips

The most frequent failure modes involve over-voltage spikes on the VINcap V sub cap I cap N end-sub The SN51DP is almost always found in a

If you are trying to troubleshoot a specific TV model, I can help you more if you tell me: The .

This pulls the voltage on the pin below the threshold, forcing the IC to ignore the faulty LED feedback and remain active.
