Sn51dp Datasheet Pdf !!top!! < OFFICIAL - RELEASE >

Resistor terminal to configure the operating current for the LED backlight strings. Pin 6 (REF): Internal reference voltage output.

The is a high-efficiency LED backlight driver integrated circuit (IC) manufactured by On-Bright. It is widely used in the power management and inverter boards of liquid crystal display (LCD) and LED televisions, notably in budget-friendly brands like Arielli, Crown, and Felix. Packaged in a compact 10-pin SSOP/MSOP configuration, this chip acts as a standalone pulse-width modulator (PWM) controller engineered to step up supply voltages and precisely regulate current through an external MOSFET.

When diagnosing issues with the SN51DP in LED backlight systems, technicians often focus on the feedback and protection pins. If the backlight fails to ignite or shuts down shortly after powering on, it may indicate that the IC has entered a protection state due to a detected fault in the LED strings or an over-voltage condition. Safe diagnostic procedures include:

LED TV drivers (found in Arielli, Crown, and Felix models), DC motor speed control, and general PWM control systems. Pinout Configuration (10-Pin) It is widely used in the power management

SN51DP is a dual-port RS-232 transceiver (or similar serial interface IC) — typically used to convert TTL/CMOS logic levels to ±V RS-232 signals for serial communication.

The SN51DP is widely used in LED backlight boards to ensure uniform lighting in televisions. Due to high-voltage operation, it is susceptible to failure if LED strips fail.
