BYN31095_AO4882&Special 30V Guide

VentureCraft is a pioneering company in this area, leading the development of high-resolution portable amplifiers, music players and headphone amplifiers, including the popular SounDroid Vantam product line. . Although high-resolution technology is only just getting started in the audio market, its evolution is already underway.

The core of power semiconductors is the PN junction. From diodes, triodes to field effect transistors, various applications are made according to the characteristics of the PN junction. Field effect transistors are divided into junction type and insulated gate type, among which the insulated gate type is also called MOS tube (Metal Oxide Semiconductor). According to whether the inversion layer exists in the case of no electricity, MOS tubes can be divided into enhancement type and depletion type.

Barrier capacitance: In power semiconductors, when the N-type and P-type semiconductors are combined, the electrons of the N-type semiconductor will partially diffuse into the holes of the P-type semiconductor due to the concentration difference, so they will form on both sides of the junction surface. Space charge area (the electric field formed by the space charge area will resist the diffusion movement, and finally make the diffusion movement reach equilibrium);

As for why not to use depletion-type MOS tubes, it is not recommended to get to the bottom of it. . For these two enhanced MOS tubes, NMOS is more commonly used.

Diffusion capacitance: When a forward voltage is applied, the non-equilibrium minority carrier concentration near the interface of the depletion layer is high, far from the non-equilibrium minority carrier concentration is low, and the concentration gradually decays from high to 0 until it reaches zero. The process of charge accumulation and release in this phenomenon is the same as that of capacitor charging and discharging, which is called diffusion capacitance. When the applied forward voltage increases, the concentration of unbalanced minority carriers increases and the concentration gradient also increases, and when the applied voltage decreases, the change is opposite.

The lithium battery is mainly composed of two blocks, the battery cell and the lithium battery protection board PCM.

The battery cell is equivalent to the heart of the lithium battery, and the lithium battery protection board is mainly composed of a protection chip (or management chip), a MOS tube, a resistor, a capacitor, and a PCB board.
