Used for: Stepping a voltage up or down ie lower or higher than the input with the same polarity
Pros:
- Steps input up to any value or down towards zero
- Simple circuit
- Easy Low-
side gate drive for main switch
- Inherently short circuit proof becasue of series capacitor
Cons:
- High output ripple -
can be > output DC current so need large low ESR output caps - Requires two inductors
- Requires high quality series capacitor
- Complex to stabilise
