- Typical Application for the A4447 is a 2 A, high efficiency general-purpose buck regulator designed for a wide variety of applications. The output voltage is adjustable from 0.8 to 24 V, based on a resistor divider and the 0.8 V ± 2 % reference. External components include an external clamping diode, inductor, and filter capacitor. The off-time is determined by an external resistor to ground. It operates in both continuous and discontinuous modes to maintain light load regulation. An internal blanking circuit is used to filter out transients due to the reverse recovery of the external clamp diode. Typical blanking time is 200 ns
