The is a specialized power management integrated circuit (IC) primarily utilized as an LED backlight driver in modern liquid crystal display (LCD) and LED televisions . Often found in popular TV brands like Arielli, Crown, and Felix , this component is critical for regulating the voltage required to illuminate the screen's LED strips. Verified Technical Specifications
Fully RoHS compliant , meeting global environmental safety standards. Pinout Configuration sn51dp datasheet verified
LED driver for backlight inverter circuits. The is a specialized power management integrated circuit
The SN51DP features a 10-pin layout designed for precise control over current and voltage protection. According to verified schematic diagrams , the pin assignments include: Pin Number Function Label Description Supply Voltage Input (often 12V) GATE Output to the external MOSFET gate OVP Over-Voltage Protection GND Circuit Ground FB Feedback for voltage regulation ISET / REF Current setting / Reference voltage CS Current Sense input COMP Compensation pin for stability OVP (secondary) Extended over-voltage monitoring DIM / PWM Dimming control (Pulse Width Modulation) Common Applications and Troubleshooting If a TV has sound but no display,
Available in MSOP-10 and SSOP-10 (10-pin) small outline packages.
If a TV has sound but no display, technicians often find that the SN51DP has failed or is receiving insufficient voltage (e.g., only 25V when more is required for the LED bulbs).
