): The maximum internal temperature of the chip. Ensure adequate PCB copper area or a heatsink is provided if running the IC near its maximum thermal capacity. 6. Primary Applications
Input Voltage. This is where your power source (e.g., a lithium-ion battery) is connected. hxje ic datasheet top
: Look for additional resources provided by the manufacturer, such as application notes, evaluation boards, or technical support contacts.
If you want, I can draft a longer blog post with an expanded introduction, a full example design using specific HXJE variant values, and diagrams (schematic + PCB layout tips).
The marking on an IC package typically refers to the (or PS3120A), a high-efficiency DC-DC step-up (boost) converter. This IC is commonly used in battery-powered devices to provide a steady 5V output from a lower voltage source. HX4004A (HX-JE) Technical Specifications The HX4004 and PS3120A are the primary cross-references
2.5 V to 5.5 V (optimized for Li-ion battery ranges).
