12Vin: -5V Output Inverting Buck Boost using Synchronous Step Down Converter Reference Design
Description
The TPS54335 provides a single IC for both control and the power stage for DC/DC applications up to 3A. PMP20566 utilizes the TPS54335 in an inverting buck boost topology to implement a regulated -5V: rail. TPS54335 enables the designer to implement power solutions which require negative voltages with low BOM count and small solution size.
