ONSEMI FAN6240M6X Synchronous Rectifier Controller

The FAN6240M6X is a high-performance secondary-side synchronous rectifier controller optimized for flyback converters operating in Discontinuous Conduction Mode (DCM). It features adaptive dead-time control, supports high-frequency applications up to 200 kHz, and includes wide voltage range capability up to 30 V for LDO inputs. Designed for efficient power management, it minimizes body diode conduction with adaptive thresholds and blanking times, ensuring robust operation against circuit noise. Its small SOT-23 package makes it ideal for compact, high-efficiency power supplies in portable electronic devices.
