While specific datasheet diagrams can be difficult to source directly, the typical SOT-23-6 boost converter layout for this family (like the HX4004) includes: Output voltage pin. GND: Ground.
Ground Reference. Central connection point for input and output loops. The IC comes integrated with robust safeguards to
: The ideal environment (voltage and current) for the chip to function reliably.
): 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 Ground Reference
HX-JE (or HX=JE depending on factory line)
The marking "HX‑JE" (or simply "HXJE") is a that identifies the specific electrical version and the production lot. Here's how to decode it:
Flying Capacitor Positive Terminal. Connection point for the charge-pump capacitor. Critical Technical Features 1. Inductorless Design
Powering peripheral interface cards.
