Sn51dp Datasheet Pdf Jun 2026

In TV repair contexts, the SN51DP is often linked to a few common issues:

If you are looking for an (often used in TV remotes and sensors), the part number is often styled as TSOP51 , VS1838B , or similar, but some manufacturers label them as SN51 series modules.

The is a high-performance LED Backlight Driver Controller typically used in LED TV and monitor backlight systems. It is often found in the power supply or backlight inverter boards of major brands like Samsung and LG.

The SN51DP operates as a pulse-width modulation (PWM) controller optimized for boost or buck-boost converter topologies. It manages the dynamic load variations common in modern LED strings. SSOP-10 / MSOP-10 (10 Pins) sn51dp datasheet pdf

Output drive signal connected to the gate of an external N-channel MOSFET. Pin 3 (GND): Common ground connection.

Let us assume you have secured the . Now, what do all those numbers mean? Here is your guided tour.

: Use the component name along with keywords like "datasheet" or "pdf" on search engines or directly on the Texas Instruments (or relevant manufacturer) website. In TV repair contexts, the SN51DP is often

– Feedback voltage input from the LED cathode array to track real-time current draw.

: The maximum output current depends on the external circuit design and the load requirements. Higher load currents (up to 1.5A or 2A) are possible with different component configurations.

The table below summarizes the essential electrical characteristics of the SN51DP. These are based on typical specifications found across various distributors: The SN51DP operates as a pulse-width modulation (PWM)
