Chip Description
The EG1397 is a high-performance controller used in half-bridge topologies, such as series resonant, parallel resonant, and LLC resonant controllers. It integrates a 650V half-bridge driver and requires fewer external components, simplifying layout. The EG1397 uses a unique architecture, including a voltage-controlled oscillator (VCO) with a maximum frequency of 500kHz, and offers flexible control modes for reliable and stable resonant mode power supplies.
The EG1397 has comprehensive protection features, with configurable settings for a wider range of applications. These include: overcurrent protection with auto-recovery, undervoltage protection, soft start, optocoupler open and short circuit protection. The configurable dead time prevents simultaneous conduction of the upper and lower bridge MOSFETs, suitable for different power applications.
