FP7209mR-G1 from Advanced Analog Technology, in a TSSOP-14-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDS	power_out	Internal LDO output that supplies internal control circuits and the gate driver. Typically regulated to ~8 V from HVDD. Bypass to GND with a ceramic capacitor.
2	DIM	input	Analog and digital (PWM) dimming control input. Accepts a DC voltage or PWM signal; the internal filter conditions the PWM into an average dimming reference. DIM start-up ~0.275 V, shutdown below 0.05 V.
3	EN	input	Enable control input. Enable threshold ~1.50 V (typ), shutdown ~1.3 V, 0.2 V hysteresis. Pull below the shutdown threshold to place the part in low-current shutdown.
4	COMP	output	Error amplifier compensation output. Connect an external RC network from COMP to GND to shape the control-loop response for current-mode boost regulation.
5	FB	input	Error amplifier inverting input / feedback pin. Regulated to VFB = 0.25 V (typ). Connect to the top of the LED-current sense resistor to close the constant-current loop.
6	OVP	input	Over-voltage protection sense input. Triggers when the pin exceeds VOVP ≈ 0.70 V (0.65-0.75 V). Drive from a resistor divider off the boost output to set the OVP trip point.
7	RT	input	Switching-frequency programming pin. Connect a resistor from RT to GND to set fOSC (100 kHz-1 MHz). RT = 51 kΩ → ~370 kHz; RT open (NC) → ~150 kHz.
8	SS	input	Soft-start programming pin. Connect a capacitor from SS to GND; internal ~3.5 µA current source charges it to ramp the internal reference and limit inrush current at start-up.
9	SC	output	LED short-circuit control pin. Works with the SCP block (VFB ≈ 0.40 V threshold, ~700 µs restart) to implement hiccup-mode protection on an LED string short.
10	CS	input	External N-MOSFET switch current-sense input. Cycle-by-cycle OCP trips at ~0.1 V; nominal current-sense regulation window VCS = 85-115 mV (typ 100 mV). Connect to the source of the switching MOSFET through a sense resistor.
11	HVDD	power_in	Main IC power supply input. Operating range 5-24 V (absolute max 26 V). Start-up voltage 2.8 V; UVLO ~2.6 V with 0.2 V hysteresis. Bypass to GND close to the pin.
12	GND	power_in	IC ground. Tie to the system ground plane together with pin 13 and the exposed pad.
13	GND	power_in	IC ground. Tie to the system ground plane together with pin 12 and the exposed pad.
14	EXT	output	External N-MOSFET gate driver output. Rail-to-rail push/pull between GND and VDS (~8 V). Typical pull-up/pull-down resistance ~0.9 Ω.
15	EP	passive	Exposed thermal pad on the package bottom. Must be soldered to the PCB ground plane for both electrical ground and heat dissipation (θJA ≈ 55 °C/W).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fp7209mr-g1.step`	305 KB	You want the bare part, or you mark your own boards.
`fp7209mr-g1-etched.step`	2.0 MB	You want the part with `FP7209mR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 519 faces against 99 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
