Frequently Asked Questions
What is the input voltage range of the TPS63020DSJR?
The TPS63020DSJR accepts an input voltage from 1.8V to 5.5V, with a nominal operating voltage of 3.6V. This range covers the full discharge curve of a single-cell Li-ion battery, making it well-suited for portable applications without requiring additional regulation stages.
What output voltage and current can the TPS63020DSJR deliver?
The TPS63020DSJR can regulate its output from 1.2V to 5.5V and supply a continuous output current of up to 3A. Its synchronous buck-boost topology ensures stable output regardless of whether the input is above or below the desired output voltage, maintaining high efficiency across load conditions.
What package does the TPS63020DSJR come in, and what applications is it suited for?
The TPS63020DSJR is available in a compact 14-pin VSON EP (exposed pad) package, which provides good thermal dissipation in a small footprint. It is ideal for smartphones, wearables, portable medical devices, IoT nodes, and any battery-powered system requiring a stable regulated voltage from a single Li-ion cell.
Are there alternative parts compatible with the TPS63020DSJR?
Compatible alternatives include the TPS63020DSJ (non-tape-and-reel variant) and other Texas Instruments buck-boost converters in the TPS6302x family. Third-party alternatives such as the Maxim MAX8819 or Richtek RT6150 may also be considered, though pin-for-pin compatibility should be verified against datasheets before substitution.
