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 | LX | power_out | Switching node / inductor connection. The drain of the internal 200mΩ low-side N-channel power FET; connect the boost inductor between the IN supply and this pin, and connect the Schottky rectifier from LX to VOUT. Absolute maximum rating -0.3V to 33V (transient +36V<50ns, -3V<10ns). |+| 2 | GND | power_in | Device ground reference and return for the internal low-side power FET. Should tie to a solid ground plane; keep the input capacitor loop back to this pin as short as possible. |+| 3 | FB | input | Current-sense feedback input. Regulated internally to VREF=200mV (196-204mV). Connect a sense resistor R1 from FB to GND at the bottom of the LED string to program the LED current: ILED = 0.2V / R1. Absolute maximum 4V; input bias current ≤1µA. |+| 4 | EN/PWM | input | Enable and PWM dimming input. Drive high (VENH≥1.5V) to enable the converter, low (VENL≤0.4V) to shut down (ISHDN≈10µA). For PWM brightness dimming apply a 20kHz-1MHz square wave; the first pulse must be ≥200ns to turn on the IC. Absolute maximum 32V. |+| 5 | OVP | input | Open-LED over-voltage protection sense pin. Monitors the boost output; when VOVP exceeds the internal clamp threshold (typ. 30V, range 28-33V) switching is inhibited to protect the circuit if the LED string opens. Absolute maximum 36V. Typically tied to VOUT. |+| 6 | IN | power_in | Input supply pin. Accepts 2.8V to 30V; UVLO rises at ~2.55V with 0.1V hysteresis. Decouple to GND with a ≥4.7µF X7R (or better) ceramic capacitor placed close to the pin. Absolute maximum 32V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-6 |+| Category | LED-drv |+| Pins | 6 |++## Ordering variants++- `SY7200AABCABC`++## CAD (KiCad official)++- Symbol: `SY7200AABC`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Silergy Corp datasheet](https://datasheet.lcsc.com/datasheet/pdf/b60d8231bdf69cbd0e7c00a3be581c69.pdf) (9 pp, sha256 `86fa6eccd7ef812c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
