cription The FAN7631 is a pulse−frequency modulation controller for high−efficiency half−bridge resonant converters that includes a high−side gate drive circuit, an accurate current−controlled oscillator, and various protection functions. The FAN7631 features include variable dead time, operating frequency up to 600 kHz, protections such as LUVLO, and a selectable latch or A/R protection using the LS pin for user convenience. The Zero−Voltage−Switching (ZVS) technique reduces the switching losses and improves the efficiency significantly. ZVS also reduces the switching noise noticeably, which allows a small Electromagnetic
