USB to 5V SEPIC DC-DC Converter with Short-Circuit Protection
The single-ended primary inductance converter (SEPIC)
shown in Figure 3 IC LT1618 is ideal for applications where the
output must reduce to zero during shutdown. The input
current limit not only helps soft-start the output but also
provides short-circuit protection, ensuring USB device
compliance even under output fault conditions.
