TPS63020 Automatic BuckBoost Step Up/Down Power Supply Module — a lowripple voltage converter designed for lithium batteries (4.2V) that provides a stable regulated supply whether the battery voltage is above or below the target. Key benefits Stable power from a single lithium cell: Automatically steps up or steps down to maintain a reliable output as the battery voltage changes during charge and discharge. Low ripple for sensitive electronics: Reduced output ripple helps prevent noiserelated problems in analog circuits, audio, RF and precision sensors. Easy to use: Module form factor simplifies integration into projects — no complex external circuitry required to get a regulated supply from a lithium battery. Protects device performance: Keeps downstream electronics within safe operating voltage ranges even as battery voltage varies. Main features and attributes Model: TPS63020 — based on the TPS63020 buckboost converter design. Functionality: Automatic buckboost (stepup and stepdown) voltage regulation to maintain a steady supply as input changes. Compatibility: Designed for lithium battery use, specified for 4.2V lithium cell operation. Performance: Delivers low ripple voltage suitable for noisesensitive applications and stable operation across the battery discharge curve. Form factor: Module style for straightforward mounting and wiring in prototypes and finished products. Ease of integration: Intended for quick connection to a lithium battery and load without the need for complex setup. Typical applications Portable electronics and development boards: Power microcontrollers, singleboard computers, and modules where battery voltage must be regulated for reliable operation. Batterypowered sensors and wireless devices: Provide stable power for IoT nodes, Bluetooth modules, and RF frontends that are sensitive to supply noise. Audio and precision circuits: Use the lowripple output to minimize audible noise and measurement errors in analog stages. Quick usage notes Connect a 4.2V lithium battery to the module input and connect your device to the module output. Observe correct polarity and secure connections before powering the module. The module is intended to provide a regulated supply as the battery voltage moves above and below the required output range — check your device's required voltage to confirm compatibility. This TPS63020 buckboost module is a practical solution when you need reliable, lownoise power from a single lithium cell without complicated design work.
