| |  |  | Description |  |  | Switching controllers offer flexibility to set output current level and limits ranging from zero to > 5amps for asynchronous designs and > 20amps channel for synchronous designs. Controller based switching regulators provide highest efficiency and performance that can be tailored to the application's requirements. Avaliable features include single and dual channels, enable, softstart, UVLO, current limit, margining, tracking, frequency synchronization, 3v-24v input voltage range, power good flag, and output accuracy to 0.5% accuracy at 25C. |  |  |  |
