Abstract

An apparatus includes a first high-side driver of a buck-boost converter, the first high-side driver powered between a first bootstrap voltage (VBST) and a first output voltage of a first high-side switch driven by the first high-side driver. A second high-side driver is powered between a second bootstrap voltage (VBST) and a second output voltage of a second high-side switch driven by the second high-side driver. A comparator is to detect VBSTdrop below a threshold value with respect to the first output voltage when the buck-boost converter is in boost mode. A leakage control circuit is to boost, using VBSTas a voltage source, VBSTeach cycle of boost mode in which an output of the comparator is enabled.
