L6920DCTR

STMicroelectronics · DC-DC Converters · MSOP-8

L6920DCTR from STMicroelectronics, in a MSOP-8. 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 FB input Output voltage selector: connect FB to GND for Vout = 5V or to OUT for Vout = 3.3V, or to an external resistor divider for an adjustable output voltage (1.8V to 5.5V).
2 LBI input Battery low-voltage detector input with an internal threshold of 1.23V; an external resistor divider is needed to set the desired low-battery threshold.
3 LBO output Battery low-voltage detector output that goes low when the LBI voltage drops below the internal 1.23V threshold; it is an open-drain output and requires an external pull-up resistor (about 200 kΩ).
4 REF output 1.23V reference voltage output; bypass to GND with a 100 nF capacitor to filter high-frequency noise, and no capacitor is required for stability.
5 SHDN input Shutdown input: the device is in shutdown when the pin is below 0.2V and operating when the pin is above 0.6V.
6 GND power_in Ground pin.
7 LX passive Step-up inductor connection (switching node) that is shorted to ground through the internal N-channel power switch during the on phase.
8 OUT power_out Power output pin, which is also the feedback reference when FB is tied to OUT for the 3.3V setting.
