L6920DBTR from STMicroelectronics, in a MSOP-8. 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 voltage selector / feedback. Tie FB to GND for Vout = 5 V fixed, tie FB to OUT for Vout = 3.3 V fixed, or connect FB to an external resistor divider from OUT for adjustable output (1.8 V to 5.2 V). FB reference is 1.23 V. |
| 2 | LBI | input | Low-battery detector input. Compared against the internal 1.23 V threshold; drive from a resistor divider off the battery to set the desired low-battery trip point. |
| 3 | LBO | output | Low-battery detector output (active-low, open-drain). Goes low when the LBI voltage falls below the internal ~1.23 V threshold. Requires an external pull-up resistor (about 200 kΩ) for correct operation. |
| 4 | REF | output | 1.23 V internal reference voltage output. Bypass to GND with a 100 nF capacitor to filter high-frequency noise; no capacitor is strictly required for stability. |
| 5 | SHDN | input | Active-low shutdown control. Device is in shutdown when SHDN < 0.2 V and operating when SHDN > 0.6 V. Shutdown current is ≤ 1 µA. |
| 6 | GND | power_in | Device ground reference. |
| 7 | LX | passive | Step-up inductor / switch node. Connects to the external boost inductor between VBATT and LX; carries the internal synchronous rectifier switch nodes. Peak switch current limit typically 0.8 A. |
| 8 | OUT | power_out | Regulated boost converter power output. Delivers 3.3 V or 5 V fixed (per FB strap) or 1.8-5.2 V adjustable; bypass with a low-ESR output capacitor (e.g. 47 µF). |
