Applications
TPS63000DRCRG4 is designed for single-cell lithium-ion powered devices such as smartphones, tablets, and wireless sensor nodes that need a stable 3.3 V or 5 V rail as the battery voltage varies from 4.2 V fully charged down to 2.5 V near depletion. Its seamless buck-boost operation eliminates the dead zone and voltage droop that plague non-overlap converter topologies, ensuring uninterrupted MCU and RF transceiver operation. The device also powers Bluetooth Low Energy modules and Wi-Fi IoT nodes that require consistent 3.3 V from a wide-range supply without dropout.

Frequently Asked Questions
What input voltage range and peak efficiency does TPS63000DRCRG4 support for Li-Ion battery applications?
TPS63000DRCRG4 accepts an input voltage from 1.8 V to 5.5 V and achieves up to 96% peak conversion efficiency. This covers the full discharge curve of a single-cell lithium-ion battery from 4.2 V fully charged to approximately 2.5 V near end-of-life, enabling continuous regulated output throughout the entire battery discharge cycle.
How does the seamless buck-boost transition of TPS63000DRCRG4 benefit portable wireless devices?
Unlike regulators with a discontinuous transition region between buck and boost modes, TPS63000DRCRG4 transitions seamlessly at the crossover point where input equals output voltage. This eliminates voltage glitches that can cause RF module resets or MCU brown-outs in devices like Bluetooth earbuds and GPS trackers, where the supply voltage passes through the 3.3 V output level during battery charge and discharge cycles.
Can TPS63000DRCRG4 power a 3.3 V rail for a Wi-Fi module drawing 500 mA peak current from a single Li-Ion cell?
Yes. TPS63000DRCRG4 delivers up to 1.2 A continuous output current at 3.3 V, which covers the 500 mA average and brief 800 mA to 900 mA transmit-burst peaks typical of 802.11b/g Wi-Fi modules. The buck-boost topology maintains regulation even as the Li-Ion cell discharges from 4.2 V through 3.3 V and down to 2.5 V without requiring a separate boost or buck stage.
What output voltage flexibility does TPS63000DRCRG4 offer for multi-rail embedded systems?
TPS63000DRCRG4 supports an adjustable output range of 1.2 V to 5.5 V set by an external resistor divider, enabling designers to configure it for 1.8 V core logic, 2.5 V DDR memory, 3.3 V MCU, or 5 V USB-peripheral rails from the same battery input. The fixed-output variant options are also available for production BOM simplification when the target voltage is known at design time.
