What are the key features of TPS61080?
- 1.2 MHz fixed switching frequency allowing use of small external inductors and capacitors for compact boost converter designs
- 2.7 V to 5.5 V input range with output up to 14 V at 400 mA, suitable for 3.3 V or single-cell Li-Ion power trees
- Automatic Burst Mode operation at light loads minimizing quiescent current for extended battery runtime in portable equipment
What is TPS61080 used for?
The TPS61080 is designed for boosting a single-cell Li-Ion or 3.3 V rail to higher voltages needed by OLED displays, white LED backlights, and piezoelectric drivers in portable consumer electronics. Its 1.2 MHz switching frequency keeps external passives small, making it a natural fit for smartphone accessories, wearables, and handheld medical devices. Industrial designers also use it to generate a stable 12 V rail from a 5 V USB input for analog sensor excitation.

Frequently Asked Questions
What input voltage range and peak output current does TPS61080 support in a boost configuration?
The TPS61080 accepts input voltages from 2.7 V to 5.5 V and can deliver up to 400 mA output current in a boost configuration with output voltages adjustable up to 14 V, making it suitable for USB-powered 12 V analog supply rails.
How does the 1.2 MHz switching frequency of TPS61080 benefit a space-constrained portable design?
The 1.2 MHz switching frequency allows the use of inductors as small as 2.2 µH and ceramic capacitors below 10 µF, shrinking the total solution size to under 9 mm² for wearable devices and miniature IoT nodes.
When should a designer choose TPS61080 over TPS61081 for a battery-powered application?
TPS61080 operates at 1.2 MHz while TPS61081 operates at 600 kHz; for applications where switching noise must stay outside an AM radio band or where 2.2 µH inductors are preferred, TPS61080's higher frequency and smaller passives offer better noise immunity and board density at the same 400 mA output capability.
