FAN7631 Datasheet | onsemi

Advanced Pulse Frequency Modulation (PFM) Controller for Half-Bridge Resonant Converters Description 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,...
