A8447 High Voltage Step Down Regulator Features and Benefits ▪ Wide input voltage range: 8 to 50 V ▪ Integrated low RDS(on) DMOS switch ▪ 3 A continuous output current ▪ Adjustable fixed off-time ▪ Highly efficient ▪ Adjustable output: 0.8 to 24 V ▪ Small package with exposed thermal pad Package: 8 pin SOIC with exposed thermal pad (suffix LJ) Description 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 ±2% reference. External components include an external clamping diode, inductor, and filter capacitor. The offtime is determined by an external resistor to ground.
