The device, with current-mode control scheme, can convert 4.5~26V input voltage to the output voltage adjustable from 0.8 to 90% VIN to provide excellent output voltage regulation. The APW7083 regulates the output voltage in an automatic PSM/PWM mode operation, depending on the output current, for high efficiency operation over light to full load current. The APW7083 is also equipped with poweron-reset, soft-start, and whole protections (incl...
