Description: High Voltage Step Down Regulator

Features

* ▪ Wide input voltage range: 8 to 50 V ▪ Integrated low RDS(on) DMOS switch ▪ 2 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) Not to scale D

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 disc
