Switch Node. This connects to the inductor and the diode. Pin 2 (GND): Ground connection. : Search for "HX" in their IC category
Building a working circuit with the HX-JE requires very few external parts. Follow this minimal configuration: This connects to the inductor and the diode
Typically 2.7V to 4.5V (optimized for Li-ion or NiMH batteries).
Some of the top manufacturers of HXJE ICs include:
The marking (often referred to as ) identifies the ) integrated circuit. This is a low-noise, constant-frequency DC-DC charge pump
