STEVAL-ISA176V1, Evaluation Board for ALTAIR05T-800, 5W wide range CV-CC optoless adapter
Referenzdesign von: STMicroelectronics
STEVAL-ISA176V1, Evaluation Board implements a 5W, 5V/1A wide-range mains battery charger with constant voltage/constant current, tailored for AC-DC chargers for mobile phones and adapters or other hand-held equipment. The core of the application is the ALTAIR05T-800, the first (all-primary sensing switching regulator) of the ALTAIR family. The IC combines a high-performance, low-voltage PWM controller chip and an 800V, avalanche-rugged power MOSFET in the same package. The PWM chip is a quasi-resonant (QR) current mode controller IC specifically designed for QR ZVS (zero voltage switching) flyback converters
