SY7069ADC from Silergy Corp, in a TSOT-23-6. 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 | FB | input | Output feedback pin. Connect to the center tap of an external resistor divider from VOUT to GND to program the output voltage: VOUT = 1.2V x (1 + RH/RL). Internal reference is 1.2V (typ). |
| 2 | IN | power_in | Signal input pin (2.5V to 5.5V). Decouple this pin to GND with at least 1uF ceramic capacitor for noise immunity. Also serves as one side of the boost inductor connection. |
| 3 | GND | power_in | Ground pin. Return for the low-side main NMOS switch and all internal circuitry. |
| 4 | OUT | power_out | Boost converter output pin (2.5V to 5.5V). Decouple to GND with at least 22uF ceramic capacitor (X5R or better, >=10V rating). Also feeds the synchronous PMOS to enable load-disconnect and auto-bypass modes. OVP triggers at 6.0V. |
| 5 | LX | passive | Inductor switching node. Connect an inductor (typ 1.5uH) between IN and LX. Internal main NMOS (RDS(ON) ~50mΩ) switches this node to GND; synchronous PMOS (RDS(ON) ~90mΩ) routes to OUT. Keep LX PCB area minimized for noise immunity. |
| 6 | EN | input | Enable pin. Pull high (>1.2V) to turn on the converter; pull low (<0.4V) to shut down (shutdown current <1uA). Do not leave floating. |
