You can download the official PDF datasheet directly from the manufacturer or major component distributors:
Dimming signal interface used to change the backlighting brightness via PWM control.
Usually VCC or NC depending on the design variant. Common Applications and Troubleshooting sn51dp datasheet pdf
: Includes on-chip 3.3V regulation, low jitter operation, and ESD protection on I/O pins.
LCD power supply Integrated Circuit (IC) / Power Management Chip Package Type: MOSP-10 / MSOP-10 You can download the official PDF datasheet directly
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
You might be tempted to find a quick pinout diagram on a forum. This is dangerous. Here is why downloading the official is non-negotiable: LCD power supply Integrated Circuit (IC) / Power
Sets the base operating current threshold for the backlight loop. Pin 7 (REF): Internal reference voltage output.
