Device-Specific Technical Discussions

In this section, some application examples with specific buck-boost devices are presented.

High Efficiency Battery Powered High Brightness LED Driver Using the TPS63000: SLVA268

This application report show how to use the TPS6300x to drive a high-brightness LED with constant current, using 1-cell Li-Ion/Li-Polymer battery or 2-/3-cell Alkaline/NiCd or NiMH batteries as the power supply.

Supercapacitor Backup Power Supply With TPS63802:SLVAE52

In this application, the TPS63802 is used to charge the backup capacitor while the main power supply is available. When the main power fails, the TPS63802 automatically supplies the system with the stored energy out of the backup capacitor. The report describes the feasibility of a backup power supply implementation with the TPS63802.

Dynamically Adjustable Output Using TPS63000:SLVA251

This application report provides a schematic and design procedure for implementing a dynamically adjustable output voltage for the TPS63000 buck-boost converter using a digital-to-analog converter or other voltage source.

How to Use VSEL Function of TPS63070:SLVAE62

Changing the output voltage of a DC/DC converter during operation can be a useful feature in battery operated applications to increase the battery lifetime. This report shows how to use the TPS63070 dynamic voltage scaling feature via VSEL pin in order to dynamically change the output voltage between two user-configurable levels.

Using Input Current Limiting to Extend Battery Life:SLVAES7

If a converter overloads the supply battery, either due to heavy load or due to inrush current during start-up, the capacity and lifetime of the battery can be significantly reduced. This application report shows how the input current limit feature of the TPS63900 can effectively limit the input current with several preset limit values, down to 1 mA, making it an ideal match for low-current coin cell batteries.

TPS63802HDKEVM - Hardware Development Kit:SLVUBU0

In this report, a universal development tool designed to help easily and quickly evaluate and test the most common buck-boost converter use cases is presented. The use cases include backup power, input current limit, LED driver, digital voltage scaling, bypass mode, and precise enable. Different use cases can be easily selected by changing jumpers and dip-switches, without any soldering.
