Often cited as the direct manufacturer part number for the HXJE marking.
Do you need assistance calculating the or choosing capacitor types?
If you are searching for the , you likely have a PCB in front of you with a tiny 5-pin or 6-pin chip labeled "HXJE," and you need its full specifications, pin configuration, and application circuit. This article serves as the ultimate resource to decode the "HXJE" top marking and find the exact datasheet.
, dropping current draw to near zero to preserve battery health. Typical Application Circuits hxje ic datasheet top
The core functionality of the HX-JE relies on an . Traditional boost converters require bulky power inductors that consume critical PCB real estate and can radiate high levels of EMI. The HX-JE circumvents this limitation by utilizing internal power MOSFETs to rapidly switch energy between the flying capacitor and the output capacitor. Non-Sensing Feedback Loop
): Fixed at (tolerances typically sit tightly between 4.8V and 5.1V). Maximum Output Current: Up to 300 mA . Nominal Driving Current: 110 mA when ; 230 mA when
: A diagram showing what each leg of the chip does (e.g., VCC for power, GND for ground). Often cited as the direct manufacturer part number
Powering LED strings, driving small motors, and providing regulated power in battery-operated consumer electronics. Sourcing & Documentation
Building a working circuit with the HX-JE requires very few external parts. Follow this minimal configuration:
While a different function (charger), it is sometimes mentioned in similar circuit repair contexts for portable audio devices. Usage Notes This article serves as the ultimate resource to
: As a charge pump, it uses capacitors rather than inductors to boost voltage, saving board space.
If you need to move forward with your hardware project, I can help you:
