Sn51dp Datasheet

The component acts as a cornerstone in budget and mid-tier LED televisions manufactured by brands like Arielli, Crown, Felix, and Hisense. It is commonly mounted on integrated power/scaler boards, notably the widely distributed .

Peak current-mode PWM control with programmable brightness dimming capabilities.

The SN51DP is generally a capable of handling medium to high power. It is most commonly found in step-down (buck) converter topologies, CRT televisions (for horizontal deflection power), and industrial power modules. sn51dp datasheet

Not suitable for phase-control dimming (e.g., light dimmers) because zero-crossing forces full-cycle switching.

Understanding the pinout is the primary reason engineers search for the SN51DP datasheet. The pin assignment (seen from the front, pins facing down) is as follows: The component acts as a cornerstone in budget

: Feedback Input. Monitors the voltage across the LED string return path resistor to ensure strict current regulation.

Compensation Pin. Typically tied to an RC filtering network to stabilize the inner loop control dynamics and prevent screen flickering. The SN51DP is generally a capable of handling
