8.1 Application Information

The LMZM33602 is a synchronous, step-down, DC-DC power module. It is used to convert a higher DC voltage to a lower DC voltage with a maximum output current of 2 A. The LMZM33602 can be configured in an inverting buck-boost (IBB) topology with the output voltage inverted or negative with respect to ground. For more details, see TI Application Report Inverting Application for the LMZM33602/03. The following design procedure can be used to select components for the LMZM33602. Alternately, the WEBENCH® software may be used to generate complete designs. When generating a design, the WEBENCH® software utilizes an iterative design procedure and accesses comprehensive databases of components. See www.ti.com for more details.
