When laying out the PCB, keep the loop area of the high-frequency switching path (Input Cap -> MOSFET -> Inductor) as small as possible to minimize EMI (Electromagnetic Interference).
The by HEXIN stands out as a reliable, highly integrated solution for stepping up voltage in compact spaces. By leveraging a non-sensing boost methodology, it allows hardware designers to create efficient, low-cost, and compact power supply stages. Always consult the official manufacturer datasheet for your specific batch or revision to ensure all resistor/capacitor values and pinouts are perfectly tailored to your design's demands.
: Often includes graphs and additional tables that provide insight into how the IC performs under various conditions. This could include efficiency, frequency response, current vs. voltage characteristics, etc.
Regulated 4.94V power output. This pin requires a small ceramic bypass capacitor placed as close to the silicon as possible to reduce transient voltage ripples.
Acts as a small-scale power rail generator to boost 3.7V lithium battery outputs to standard 5V logic lines for MCUs and peripherals.
The (often marked as HX-JE or HX=JE ) is a high-efficiency DC-DC step-up (boost) converter integrated circuit typically found in a SOT-23-6 package. It is widely used in small portable electronics to provide stable voltage to components from lower-voltage sources like single-cell batteries. Technical Specifications
Requires only small ceramic capacitors for operation, saving PCB space. Protection:
Explore depending on your exact voltage input and output requirements.
While specific datasheet specs can vary by manufacturer, specialized boost ICs like the HX-JE generally include under-voltage lockout (UVLO), thermal shutdown, and over-current protection to ensure safe operation. Pin Configuration and Functions
