360 kHz , enabling low-noise performance and predictable ripple profiles.

At its core, the chip marked "HX-JE" (also referred to as HXJE) is a low‑noise, regulated . It uses a switched‑capacitor voltage‑doubling technique to step up a lower input voltage (2.5 V–5 V) to a stable 5 V output. The most common underlying parts that use this marking are the HX4004A (from HEXIN) , the HU3031B , and the PS3120A —all functionally interchangeable in most applications. hxje ic datasheet top

Check the voltage levels across the bypass capacitors directly touching and Pin 1 ( VOUTcap V sub cap O cap U cap T end-sub ) using a digital multimeter. VINcap V sub cap I cap N end-sub is between 2.7V and 4.5V but VOUTcap V sub cap O cap U cap T end-sub stays close to or matches VINcap V sub cap I cap N end-sub

Remember that while the peak current can reach 300 mA, the safe continuous load drops down to if your source battery sags down to 3.0V. Exceeding these design boundaries triggers internal thermal protection safeties. : Would you recommend the product to others

Based on the identifier this component refers to a series of High-Voltage LED Driver and Power Switcher ICs (commonly found in solid-state lighting and compact power supply designs). These chips are typically manufactured by cost-effective semiconductor foundries and are widely used in the consumer electronics market for driving LED arrays and managing low-power AC-to-DC conversion.

The marking code represents the HX4004A (specifically the HX4004A-MF or HX4004A-MFC variant), a high-efficiency, low-noise, regulated charge pump DC-DC step-up converter . Alternatively, the identical "HX=JE" surface marking is shared by the PS3120A voltage doubler, functioning as a pin-to-pin compatible replacement. This specialized component uses an inductorless "non-sensing" design inside a compact SOT23-6 package to boost low lithium-ion battery voltages up to a stable 5V output. Core Specifications Overview At its core, the chip marked "HX-JE" (also

: While "HXJE" is the marking code, similar parts from this manufacturer (HXJ) are often found in SOT23-6 , SOP8 , or SOP16 packages.

The (primarily known by its full manufacturer part numbers HX4004 or HX4004A ) is a highly sought-after, low-noise, regulated charge pump DC-DC boost converter. Manufactured by Hexin Semiconductor, this component is widely recognized in engineering and electronics repair circles by its top-side SMD marking code: HX=JE (or HX-JE). Packaged in a compact SOT-23-6 format , it is an inductorless voltage doubler and step-up chip designed to deliver a fixed 5V output from low-voltage inputs, typically sourced from lithium-ion batteries.
