TPS63020 Boost Buck Power Module for Microcontrollers, 1.8-5.5V Input, Low Ripple

Power Supply Module for Microcontroller Projects This compact boost-buck power module delivers a dependable 1.8–5.5V input range, making it well suited to powering STM32, ESP32, 51 microcontrollers and similar development boards. Built around the TPS63020 voltage conversion IC, it provides stable output with low ripple and a switching frequency of up to 2.4MHz, so your projects receive clean, consistent power during operation. Reliable Performance for Everyday Use In most operating conditions, the module can supply an output current above 900mA, giving you ample headroom for sensors, displays and other peripherals. The red LED output indicator lets you see at a glance when power is flowing, which is particularly handy when debugging circuits or checking connections on a bench setup. Flexible Power Saving Options You can choose between normal operation and a power saving mode, allowing the module to reduce consumption when full performance is not required. This helps extend the battery life of connected input devices, making the module a practical choice for battery-powered builds where efficiency matters. The module uses a straightforward up/down structure, so it can step voltage up or down as needed, and its black PCB keeps the design neat and easy to integrate into your existing projects.
