, specifically designed for use in liquid crystal display (LCD) applications.
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. sn51dp datasheet pdf
Based on the schematic data, the 10-pin layout is standard for many DC-DC boost controllers: Pin # Power supply input (typically 12V). DIM Dimming control input (PWM or DC voltage). GATE Drive signal output for the external N-Channel MOSFET. GND Ground reference. CS Current sense input (connects to source of MOSFET). REF/ISET Internal reference voltage or current setting pin. FB Feedback pin for monitoring LED current. COMP Compensation pin for stability of the control loop. OVP Over-voltage protection sense pin. GATE_OVP , specifically designed for use in liquid crystal
Potential applications for the SN51DP include: Packaged in a compact 10-pin SSOP/MSOP configuration, this
Supports both analog dimming and digital PWM dimming interfaces.
It is designed to handle demanding environments, with a maximum operating temperature of 85°C to 130°C depending on specific batch tolerances.
