COO (Country of Origin):

The STEVAL-ISA176V1 evaluation board implements a 5 W (5 V / 1 A) 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 800 V, 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 at switch turn-on) flyback converters. The device is capable of providing constant output voltage (CV) and constant output current (CC) regulation using primary-sensing feedback. This eliminates the need for the optocoupler, the secondary voltage reference and the current sensor, while still maintaining quite accurate regulation.
