Description

A Two-Switch Boost-Buck Converter is a DC-DC converter whose output voltage can be greater than, equal to or lesser than the input voltage supply. This is different from a SEPIC type Boost-Buck converter in that it has two switches, two diodes, one inductor and no coupling capacitor. The control circuit is, however, more complex as it requires two comparators and two ramp signals to generate two PWM control signals for two switches.
