Understanding resistance element

Resistors, also known as resistors, belong to current limiting devices. In daily design and development, resistors are mainly used to limit current and partial voltage. Understanding resistance is very important in circuit design. There are many kinds of resistors, which can be classified from materials, packaging and uses. From the material, mainly thin film resistance,…

What are the common capacitors?

Today, Xiaobian to introduce three common capacitors, let's take a look ~ 1, aluminum electrolytic capacitor Using absorbent paper dipped in paste electrolyte sandwiched between two pieces of aluminum foil winding, thin oxide film as a dielectric capacitor. The electrolytic capacitor has polarity because of the unidirectional conductivity of the oxide film. Large capacity, can…

Common-mode inductor

Common-mode inductor

Working principle of common mode inductor Common mode inductance In a circuit, when a differential mode signal passes through a common mode inductor, the magnetic flux produced by the differential mode signal in the core is equal in magnitude and opposite in direction. The net flux is zero, so the common-mode inductance to the differential…

PMU driver for microcontroller ballast

PMU driver for microcontroller ballast

L6382D5 is suitable for embedded PFC and half-bridge microcontrolled electronic ballasts. The L6382D5 includes four MOSFET driver stages (for PFC, half-bridge, and preheated MOSFET) and a power management unit (PMU), which also has a reference that can power the microcontroller in any situation. In addition to improving application efficiency, the L6382D5 also reduces material costs…
