Description

This design note describes an output converter for battery-powered and automotive applications. It uses a UCC3803 BiCMOS current-mode controller to provide a 5V output at full load of 100mA from an input of 2.5-13.5V after an initial startup at 5V. The UC3803 is part of the UCC1800/1/2/3/4/5 family of high-speed low-power integrated circuits which contains all necessary control and drive compone
