The A8447 is a 3 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 3% reference. External components include an external clamping diode, inductor, and filter capacitor. The offtime 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.
This device is ideal for various end products including applications with 8 to 50 V input voltage range and require up to 3 A output current, such as uninterruptible power supplies, point of sale (POS) applications, and industrial applications with 24 or 36 V bus.
The A8447 is supplied in 8 pin SOIC with exposed thermal pad (suffix LJ). It is lead (Pb) free, with 100% matte-tin leadframe plating.
