Flyback converters are versatile power electronics devices used in applications such as medical devices and laptops. Also known as isolated buck-boost converters, these converters are simple circuits that can regulate a system’s output voltage (VOUT) while minimizing electromagnetic interference (EMI). This article will introduce flyback converters, and explore their topology, useful parameters, ...

To meet the increasingly stringent requirements for environmentally friendly solutions, MPS’s AC/DC power supply products utilize advanced technologies to enhance performance and achieve energy conservation. This article is the second in a two-part series to discuss trend-setting AC/DC solutions. Part I served as an introduction for the carbon-free era and the problems that designers face with tr...

The demand for fast charging has driven the unprecedented evolution of high-density adapters. In practical adapter designs, there are countless implementations of new switching power devices, topologies, and control schemes. With the introduction of these cutting-edge technologies, the power density of adapter products has significantly increased. 1W/cm3 is becoming the common density for high-de...

The flyback power supply is one of the most commonly used topologies. Typically, the transformer’s leakage inductance causes primary-side ringing, which generates voltage spikes that damage the MOSFET. It is essential to design the transformer and MOSFET components to control ringing. MPS has introduced an RCD clamp circuit design strategy to reduce leakage inductance. This circuit is described in...

As modern devices become smarter and more customizable, consumers are also demanding that they be smaller and more powerful. This has driven demand for technology that can manage thermals with ever-higher power densities as processing power increases. MPS is innovating and creating highly integrated converters and controllers with cutting-edge efficiency and power density. By integrating the entir...

Due to their versatility, ease of design, and low cost, flyback converters have become one of the most widely used topologies in power electronics. Its structure derives from one of the three basic topologies — specifically, buck-boost topology. However, unlike buck-boost converters, flyback topologies allow the voltage output to be electrically isolated from the input power supply. This feature i...

Infrared (IR) and remote frequency (RF) home remote controls are being used in systems such as sound systems, televisions, lighting, and other controls. These systems are becoming increasingly complex with features including voice control, connectivity, LED displays, and capacitive touch. Remote controls should be reliable, easy to use, and have a long battery lifespan. MPS provides cost-effectiv...
