a fixed 5V output, and the second switching controller controller (Channel 2) features a fixed 3.3V output. Both channels can also be independently adjusted from 1.3 to 5.5V. The adjustable linear regulator can be adjusted from 3.3V to 15V. An internal 5V rail is also available externally for driving bootstrap circuitry. This rail also serves as the input for an internal LDO that provides the fixed 3.3V/50mA output rail. Current-mode feedback control assures excellent line and load regulation an.
