TPS61022RWUR boost converter 2A synchronous step-up regulator
The TPS61022RWUR is a high-efficiency, synchronous boost converter from Texas Instruments (TI), designed to step up input voltages as low as 0.9V to a regulated output of up to 5.5V at currents up to 2A. Housed in a compact 10-pin WSON (2mm × 2mm) package with 0.4mm pitch, it is optimized for space-constrained applications requiring high power density. Key features include 95% peak efficiency, programmable soft-start to minimize inrush current, and true shutdown mode (<1µA quiescent current) for extended battery life. The device integrates low-RDS(ON) MOSFETs, reducing conduction losses and eliminating the need for external diodes, while its adaptive output current limit protects against overloads in dynamic workloads.
TPS61022RWUR Applications
The TPS61022RWUR excels in low-input, high-output current boost conversion scenarios, including:
1. Wearable Devices: Powering displays, sensors, and wireless modules in smartwatches and fitness trackers.
2. Portable Medical Instruments: Providing stable 5V rails for glucose meters and pulse oximeters from single-cell Li-ion batteries.
3. IoT Edge Nodes: Driving RF transceivers and microcontrollers in battery-operated smart sensors.
4. Audio Accessories: Boosting voltage for headphone amplifiers in Bluetooth earbuds and hearing aids.
