Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design.
The flyback converter is an isolated switching power
With un-tethered instant access to data, news and entertainment, consumers are spending more time on Smartphones and mobile devices. Device users are demanding faster connectivity, multi-core Ghz+
Due to the constant evolution of consumer electronics, efficient power conversion is critical for reliable performance, and the filtering of output ripple is a critical factor in supplying consistent
Mobile battery capacity is increasing to cope with the extra energy demands of power-hungry features, larger displays and more powerful CPUs. With bigger batteries to charge, how can system designers
As Power Factor Correction (PFC) migrates to lower power AC/DC converters, maintaining efficiency at low loads becomes an increasing challenge. The approach usually taken involves adding an extra
For more than a decade, development of Infineon's CoolMOS™ super-junction (SJ) MOSFET technology has extended the "silicon limit line" that restricts the performance of planar-type power MOSFETs.
