STEVAL-ISA132V1 Datasheet PDF - STMicroelectronics

Description
The STEVAL-ISA132V1 evaluation board implements a converter capable of delivering 170 W of continuous power (VIN = 190 VAC to 264 VAC, VOUT = 24 V) and more than 300 W peak power for a limited time. The architecture of the board is based on a single-stage LLC resonant converter without PFC using the new L6699 resonant controller. The L6699 integrates some very innovative functions such as self-adjusting adaptive dead-time, anti-capacitive mode protection and proprietary “safe-start” procedure preventing hard switching at startup.
