This application note presents a step-by-step design procedure and guidelines for off-line flyback converters using Fairchild Power Switch (FPS). The design process was made more efficient with the ...

Compared to conventional hard-switched converters with fixed switching frequencies, the quasi-resonant converter (QRC) topology is a very attractive alternative for power supply designers. The ...

Peter Green explains advantages of LED drivers based on the flyback power-supply topology: They're inexpensive; they provide an isolated output that complies with UL safety requirements; they make it ...

In low-power USB and offline wall adapters, quasi-resonant and discontinuous current mode flyback converter topologies are a popular choice due to their low parts count and relatively low cost.

Flyback converter technology remains pivotal in modern power electronics, offering a versatile solution for a broad range of applications from consumer electronics to industrial power supplies. Recent ...

Figure 1 shows the architecture of a conventional isolated flyback converter. These converters can be found frequently in power classes of up to about 60W. A supply voltage is converted to an output ...

In some circuits, galvanic isolation is necessary due to safety considerations. In other circuits, functional isolation is used to block any interference on signals. A galvanically isolated power ...

Zetex Semiconductors has introduced a dedicated rectifier controller for driving MOSFETs so that they perform as ‘ideal diodes’ in synchronous flyback converters ranging from 50 to 150W. According to ...

Analog-controlled power supplies are widely used in small- to medium-power industrial applications, such as industrial robots and semiconductor manufacturing equipment. However, growing demands for ...

KYOTO, Japan, Sept. 18, 2025 /PRNewswire/ -- ROHM Co., Ltd. has developed a new reference design (REF67004) that uses a single MCU to control two commonly used power-converter types for consumer and ...
