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.
- Inverting buck-boost topology using synchronous, step-down converter
- Internal MOSFETs allows for reduced BOM count and smaller solution size
- Current mode control with external COMP pin enables greater design flexibility
- Pulse skipping to maximize efficiency in light load conditions
