WebMaxim Integrated MAX17691A and MAX17691B Isolated Flyback Converters are high-efficiency no-opto integrated nMOSFET flyback converters that uses fixed frequency peak current mode control. The devices sense the isolated output voltage directly from the primary-side flyback waveform during the off-time of the integrated nMOSFET. WebThis is the case for the most commonly used flyback converter control technique: peak current control mode (see Figure 4). Figure 4: Peak Current Control Mode Schematic Primary-Side and Secondary-Side Regulation The main problem that arises with flyback converters is the preservation of isolation.
