APS2420ATBER

Wuxi Chipown Micro-electronics · DC-DC Converters · SOT-23-5L

APS2420ATBER from Wuxi Chipown Micro-electronics, in a SOT-23-5L. 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 EN input Regulator enable control input: above 1.1 V it turns the regulator on, below 0.6 V it turns the regulator off, and it must not be left floating.
2 GND power_in Ground pin.
3 LX output Power output switch node connected to the external inductor and to the drains of the internal P-channel and N-channel MOSFET switches.
4 VIN power_in Power supply input pin that must be tightly decoupled to ground with a 22 µF or larger ceramic capacitor.
5 FB input Feedback input pin connected to the midpoint of the external resistor divider; the feedback threshold voltage is 0.6 V.
