If you are looking for the , it is generally found within electronics repair forums and component supplier sites specializing in LCD backlight driver ICs. Key Technical Specifications of SN51DP Based on typical application circuits, the features the following specifications:
Suggest if you can't find this exact model.
This configuration is a standard topology, which takes a lower input voltage (e.g., 12V) and "boosts" it up to the required backlight voltage (e.g., 71V, 115V).
If you are looking to fix a specific board or source components, let me know: What is the television or monitor? sn51dp datasheet pdf
Current setting pin. Fixes the default reference current value through a precise ground-tied resistor. CS
The SN51DP pinout is critical for troubleshooting and repair: Power Input. PWM-DIM: PWM Dimming Signal Input. GATE: Gate Drive Output for external MOSFET. GND: Ground. CS/FB: Current Sense/Feedback pin for current regulation. ISET: LED Current Setting Pin. REF: Reference Voltage. COMP: Compensation Pin for boost converter stability. OVP: Over Voltage Protection Input.
The "DP" suffix indicates a plastic DIP. Count the pins. Typical DIP packages are 8, 14, or 16 pins. The datasheet will show pin 1 location (usually marked by a dot or notch). If you are looking for the , it
: Typically RoHS compliant, meeting commercial environmental and manufacturing standards. SN51DP Pinout Configuration Breakdown
The SN51DP datasheet PDF provides detailed technical specifications, including:
If you are repairing a device that contains an SN51DP, here is how to use the datasheet to fix it. If you are looking to fix a specific
While a definitive "SN51DP datasheet PDF" from a primary source like Texas Instruments or STMicroelectronics does not exist, the combined technical intelligence from the field is more than sufficient. The SN51DP is a vital component in modern LED TV backlight systems, and a deep understanding of its pinout, protection features, and typical application circuit empowers engineers and technicians to design with it or, more commonly, to troubleshoot and repair it.
The Darlington pair configuration multiplies the current gain, meaning you can drive heavy loads without needing additional driver transistors or MOSFETs.
Current sense input used to monitor inductor peak current for cycle-by-cycle protection.
Generates the necessary voltage levels for LCD operation, including driving voltages (VGH, VGL, AVDD).
