For circuit modifications where an alternative footprint is acceptable, the SN51DP circuit behavior closely mirrors the widely available OB3350CP LED Controller . However, note the structural package variance: Package profile uses a 10-pin SSOP layout . OB3350CP: Package profile uses a smaller 8-pin SOP layout .

| Pin | Name | Function Description | |-----|------|----------------------| | 1 | VIN / VDD | Main power supply input. Typical voltage in active mode: 12 V. The chip can accept between 4.5 V and 28 V | | 2 | GATE / DRV | Gate drive output for the external N‑channel MOSFET. This pin provides the switching pulses that control the boost converter | | 3 | GND | Ground reference for the IC | | 4 | ISENSE / OCP | Over‑current protection sense input. Connected to a current‑sense resistor in the source path of the MOSFET | | 5 | REF / VREF | Reference voltage input or set point. Typically receives a 2.5 V reference signal from the main processor or an external voltage divider | | 6 | COMP / Compensation | Frequency compensation network connection (RC network to ground) | | 7 | FB / LED_FB | LED current feedback. This pin senses the voltage across the LED string to regulate output current | | 8 | NC / Not Connected | No internal connection (may be left open) | | 9 | OVP | Over‑voltage protection sense input. Monitors the boosted LED+ voltage through a resistive divider. Normal operating voltage at this pin ≈ 1.55 V.
