High efficiency step-down switched capacitor DC-DC converter
The power requirement for vehicles increased continuously in the 20th century as consumers required more from their vehicles; car manufacturers have provided both standard and optional equipment to meet these demands. In addition, during the last 25 years, government legislation for emissions and sa...
