SLLS654C April 2005 – December 2014 MC33063A-Q1
PRODUCTION DATA.
NOTE
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
The MC33063A-Q1 device requires minimal external components to build converters in the boost, buck, and inverting topologies.
