If the backlight flashes and then shuts down, the OVP or ISET pins may be triggering shutdown due to a faulty LED string.
Integrated 3.3V regulator and low-jitter operation. 2. Pinout Configuration (MSOP-10)
Depending on the manufacturer layout, pin-to-pin compatible replacements often include specific power controllers from brands like Texas Instruments (TPS series), Richtek (RT series), or Silergy (SY series). Always verify the pinout configuration in your specific schematic before swapping components.
The specifications below represent the performance metrics of the SN51DP under standard operating conditions ( , unless otherwise noted). Power Supply Performance 4.5V to 18V Quiescent Current ( IQcap I sub cap Q
The "exclusive" nature of the often stems from it being a specialized component used primarily in proprietary or OEM equipment rather than general-purpose electronics.
When you download the official PDF document, focus on these critical sections to ensure successful circuit integration: 1. Absolute Maximum Ratings
However, . Major components distributors list the SN51DP under multiple manufacturers, including ON-Bright, ON Semiconductor (ONSEMI), and MPS (Monolithic Power Systems) . Always verify the manufacturer and the specific batch or date code (e.g., "15+" indicates a 2015 batch) to ensure the authenticity and lifecycle status of the part.
Enable input. A logic high activates the chip; a logic low forces the device into an ultra-low-power sleep state.
This matrix outlines the minimum, typical, and maximum parameters verified during factory testing. Use the typical values for standard circuit calculations and the worst-case boundaries for safety-margin design. 3. Typical Application Diagrams
