The marking on an integrated circuit (IC) typically identifies the HX4004 (or HX4004-MFC), a high-performance DC-DC Step-Up (Boost) Converter . Technical Specifications
If the IC gets abnormally hot or cuts out intermittently, calculate your total output current draw. hxje ic datasheet top
The internal block diagram of the HXJE reveals a streamlined architecture focused on reliability: The marking on an integrated circuit (IC) typically
For designers requiring a streamlined, efficient boost converter that avoids the inefficiencies of current-sensing resistors, the offers a compelling solution. Its specialized non-sensing nature allows for simpler schematics, reduced component counts, and higher efficiency in portable power applications. When looking for the best performance in compact power systems, the HX-JE is a "top" contender in the specialized IC market. bulk procurement options
Non-sensing boost / Voltage doubler that requires only external capacitors, making it an "inductorless" solution. Pinout Configuration (SOT-23-6)
