AP2004HTCER-ADJ

Wuxi Chipown Micro electronics · DC-DC Converters · SOT-23-6L

AP2004HTCER-ADJ from Wuxi Chipown Micro electronics, in a SOT-23-6L. 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 SW output Switching pin that connects to the external inductor; the datasheet gives an SW absolute maximum of -0.3V to +12V.
2 GND power_in Power ground; the VIN bypass capacitor must be connected closely between VIN and this pin.
3 FB input Feedback input connected to the center point of the external resistor divider, with a feedback threshold of 0.6V; absolute maximum -0.3V to +6V.
4 SHDN input Chip shutdown input where logic high is normal operation and logic low is shutdown; it must not be left floating and its absolute maximum is -0.3V to +6V.
5 VIN power_in Power supply input with an operating range of 2.5V to 5.5V, which must be closely decoupled to GND (pin 2) with a 10µF or larger ceramic capacitor; absolute maximum -0.3V to +6V.
6 NC unconnected No internal connection.
