Applications
TPS62260ADRVR is optimized for battery-powered portable electronics such as fitness bands, wireless sensors, and handheld instruments that require efficient regulation from a single-cell Li-ion or USB 5 V supply. Its 600 mA output capability is sufficient for powering ARM Cortex-M microcontrollers, Bluetooth SoCs, and accompanying peripherals from a minimal footprint. The device is also used in industrial IoT nodes and medical wearables where board space and battery runtime are both critical constraints.

Frequently Asked Questions
Can TPS62260ADRVR supply a Bluetooth SoC and an MCU simultaneously from a single-cell Li-ion battery?
TPS62260ADRVR supports input voltages from 2.5 V to 6 V, directly compatible with a single-cell Li-ion battery discharging from 4.2 V to 3.0 V. With up to 600 mA output current, it can supply a Bluetooth SoC consuming 50 mA to 100 mA and an ARM Cortex-M MCU at 50 mA to 150 mA, leaving significant margin for sensors and LEDs, all from a single power rail conversion in one compact 6-pin package.
How does the 95% peak efficiency of TPS62260ADRVR affect battery runtime in a wearable device?
At 95% peak efficiency, only 5% of input power is lost as heat, meaning a 50 mA load at 3.3 V output draws approximately 52.6 mA from a 3.7 V Li-ion cell rather than the 75 mA a 67% efficient linear regulator would require. Over a 500 mAh battery, this efficiency difference extends runtime by over 30%, translating to several additional hours of operation in always-on fitness trackers and IoT sensor nodes.
How does TPS62260ADRVR compare to a low-dropout linear regulator for a 5 V USB to 3.3 V conversion?
A linear regulator dropping 5 V to 3.3 V dissipates 1.7 V × load current as heat — at 300 mA that is 510 mW, requiring heatsinking or derated operation. TPS62260ADRVR with 95% efficiency dissipates only about 26 mW at the same 300 mA load, eliminating thermal hotspots on compact PCBs. The switching converter costs slightly more per unit but removes the need for a heatsink, enabling smaller form factors with sustained 600 mA load capability.
