integrated circuit typically found in consumer electronics like portable Bluetooth speakers and power banks. It is widely used in Chinese-manufactured electronics as a low-cost solution for generating a regulated 5V rail from a lower lithium-ion battery voltage (3.0V–4.5V). The HX-JE is frequently cross-referenced with the 🛠️ Technical Specifications Based on the datasheet for the Go to product viewer dialog for this item.
To wire the HX-JE correctly, you need to understand its 6-pin layout. While minor variations can occur depending on the specific revision of the component, the general configuration is as follows:
The is a widely utilized, highly efficient component in modern electronics, most commonly serving as the surface-mount package marking for the HX4004 / HX4004A and PS3120A power management chips . Primarily manufactured by HEXIN Semiconductors and housed in a compact SOT23-6 package, this device functions as a low-noise, regulated charge pump DC/DC converter and inductorless step-up boost IC. It is an essential component for engineers designing battery-powered consumer electronics, LED backlighting modules, and portable wireless systems.

Position the flying capacitor as close to Pins 5 and 6 as physically possible. Long trace lines act as antennae, inducing high-frequency ringing.
Flying Capacitor Positive Terminal. Connection point for the charge-pump capacitor. Critical Technical Features 1. Inductorless Design
Applying a controlled, low-power current-voltage (I-V) sweep to the pins of the "HXJE" IC against the ground pin maps out the internal ESD (Electrostatic Discharge) protection diodes. This helps identify digital I/O pins, power pins, and analog inputs before ever powering on the device. 4. Phase III: Advanced Imaging and Silicon Decapsulation To wire the HX-JE correctly, you need to

Since "HXJE" is just the marking, you need the . Here are the top reliable sources:
The HX-JE operates as a constant-frequency power IC, eliminating the need for an external inductor. It relies exclusively on a single flying capacitor to achieve step-up voltage regulation. Operating Specification 2.7V to 4.5V Regulated Output Voltage ( VOUTcap V sub cap O cap U cap T end-sub ) 4.94V DC ( Switching Frequency Constant 360 kHz (Low Noise) Peak Output Current ( IMAXcap I sub cap M cap A cap X end-sub ) Up to 300 mA Continuous Current ( ) Continuous Current ( ) Quiescent Current (No Load) 0.17 mA (Typical at Operating Temperature Range Pinout Configuration (SOT-23-6 Package Top View) It is an essential component for engineers designing
One of the first things hardware engineers check in an IC datasheet is the . For the HX-JE, the schematic is typically straightforward, requiring only a handful of external passive components:
