INTRODUCTION
Virtually all of today's electronic systems require some form of power conversion.
The trend toward lower power, portable equipment has driven the technology and
the requirement for converting power efficiently. Switchmode power converters,
often referred to simply as switchers, offer a versatile way of achieving this goal.
Modern IC switching regulators are small, flexible, and allow either step-up (boost)
or step-down (buck) operation.
