Description
- TEVAL-ISA105V1, Demonstration Board implements a power supply based on a quasi-resonant mode of operation using ST primary side ALTAIR04-900 flyback switch. The ALTAIR04-900 is a high-voltage all-primary sensing switcher intended for operating directly from the rectified mains with minimum external parts. It combines a high-performance low voltage PWM controller chip and a 900 V avalanche-rugged power section in the same package. The controller is a current-mode specifically designed for offline quasi-resonant flyback converters. The device is capable of providing constant output voltage using all primary sensing feedback
