In the evolution of electronic products, users are always expecting longer battery life. However, the increasing functionality on one hand and the shrinking device size on the other have become “roadblocks” to improving battery capacity, keeping it in a state of “tight balance.” This makes battery life a key competitive factor for consumer electronics, medical electronics, and communication modules.

Since its launch, ITECH’s IT2700 Multi-Channel Modular Power System has gained rapid adoption across research laboratories and production lines worldwide. With its flexible configuration of power supply, bidirectional source, regenerative load, and SMU (source measure unit) modules — all within a compact 1U high-density design — the IT2700 has proven itself as a versatile, efficient, and reliable testing solution.

BJT, or bipolar transistor, commonly known as triode, is an electronic device with three terminals, made of three parts of semiconductors with different degrees of doping, and the charge flow in the transistor is mainly due to the diffusion of carriers at the PN junction and the drift motion. Bipolar transistors are capable of amplifying signals and have better power control, high-speed operation, and durability, so they are often used to form amplifier circuits or to drive devices such as speakers and motors, and are used in a wide range of applications such as aerospace engineering, medical devices, and robotics.

In the evolution of electronic products, users consistently expect longer battery life. Yet, while functions continue to increase, product sizes shrink—creating a constant “bottleneck” that keeps battery capacity in a state of delicate balance. As a result, endurance has become a key competitive factor for consumer electronics, medical devices, and communication modules.

High-voltage, high-power capacitors are key components in modern power systems. Market demand continues to grow, driven by the rapid development of renewable energy generation (wind and solar), electric vehicles, smart grids, and industrial variable-frequency equipment. These capacitors must offer high voltage endurance, large capacitance, low loss, and high reliability to support critical functions such as energy storage, filtering, and reactive power compensation.

Background Power management ICs (PMICs) and DC-DC converters serve as the 'energy hub' of electronic systems, responsible for power conversion, distribution, monitoring, and management. They deliver precise voltages to various loads, enable efficient charging, and enhance overall system performance.
