Package : DIY Module Model Number : TPS63020 Dissipation Power : ... Supply Voltage : 1.8V-5.5V Application : Computer Type : Voltage Regulator Origin : China Condition : New Operating Temperature : -40℃~+80℃ Functions : Electronic Module Range of application : Switch And Sensor For Arduino STM  TPS63020 is a high-efficiency small buck-boost power supply module. The input voltage ranges from 1.8V to 5.5V, the output current can be as high as 3A, and the efficiency is as high as 96%. It can automatically switch between buck and boost modes. The quiescent current is less than 50uA and the fixed operating frequency is 2.4. mhz, can be used for all two-cell and three-cell alkaline batteries, single-cell lithium battery powered devices, ultra-small mobile PCs and MIDs, digital media players, DSCs and cameras.  Product Parameters: Input voltage: 1.8V-5V (recommended input above 2V)Output voltage: 2.5V 3.3V 4.2V 5VOutput formula: R3 = R1 (Vout/VFB-1) typical value VFB = 500mV (2.5V: R1 = 82K, R3 = 330K; 3.3V: R1 = 180K, R3 = 1M; 4.2V: R1 = 3K, R3- 22K; 5V: r1 = 110K, R3 = 1M)Output current: within 3AConversion efficiency: 96% (the smaller the input and output pressure difference, the higher the efficiency)Static power consumption: 6mA, 50uA (power saving mode)Switching frequency: 2.4mhzOutput ripple: 10mV (no load) 10mV (buck with 0.5A) 30mV (boost with 0.5A)PS: Point-saving mode (1 is disabled, 0 is enabled, and the module is disabled by default). If you want to use this function, you need to disconnect SB1, and then input the levelEN: Enable input (1 is enabled, 0 is disabled, and the module is enabled by default). To use this function, disconnect SB2, and then input the levelPG: output status indication (0 fault, 1 normal) The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability. In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals. All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction. This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
