Users often share rare or obsolete datasheets. The SN51DP is a high-performance LED driver IC

The IC features 10 pins designed for power management and dimming control : Pin Number Function Description 1 VIN Input voltage (typically 12V in backlight circuits) . 2 DIM Dimming control signal input . 3 GATE Drive signal output for the external MOSFET . 4 GND System ground . 5 CS Current sense input to monitor LED string current . 6 ISET Current setting pin (often uses a reference resistor) . 7 FB Feedback pin for voltage/current regulation . 8 COMP Compensation pin for stability of the control loop . 9 OVP Over-voltage protection . 10 REF Reference voltage output . 💡 Practical Application Tips 2 DIM Dimming control signal input

These features make the SN51DP an excellent choice for isolated power supplies requiring up to 50W of output power.
