FP7209XR-G12 from Advanced Analog Technology, in a SOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDS | power_in | Power supply for internal control circuits and gate drivers, regulated to 7.5V to 8.5V (8.0V typical) at HVDD=12V and IDS=0A, with EXT pull-up and pull-down resistance specified at VDS=8V. |
| 2 | DIM | input | Analog and digital dimming control input that accepts a DC voltage (0.275V to 2.7V valid range) or a PWM signal, shuts the part down below 0.05V, is clamped internally at 2.7V, and must not float in normal operation. |
| 3 | COMP | output | Compensation pin of the error amplifier, used with an external compensation network to stabilize the current-mode control loop. |
| 4 | FB | input | Error amplifier inverting input referenced to the internal 0.25V reference, with feedback voltage of 0.2475V to 0.2525V for the FP7209XR-G12, and LED current set by a sense resistor from FB to GND. |
| 5 | OVP | input | Over-voltage protection input, set by a resistive divider from LED+ so that EXT is turned off when OVP exceeds the 0.65V to 0.75V threshold (0.70V typical). |
| 6 | CS | input | MOSFET switch current-sense input, where the sense voltage is 85mV to 115mV and the current limit resistor RCS connected between CS and ground sets the peak inductor current. |
| 7 | HVDD | power_in | IC power supply input with a 5V to 24V operating range, 2.8V start-up voltage and 2.6V undervoltage lockout threshold. |
| 8 | EXT | output | Gate driver output for the external N-MOSFET switch, with pull-up and pull-down resistance of 0.6Ω to 1.2Ω at VDS=8V. |
| 9 | GND | power_in | IC ground on the exposed pad (EP), which must be connected to ground. |
