DC-DC Automatic Step Up-down Power Module (2.5~15V to 3.3V 600mA)

This remarkable power module offers automatic buck - boost functionality and comes integrated with the relevant buck - boost converter circuit. Its compact size makes it a breeze to embed in various projects. With an input voltage range from 2.5V to 15V and a fixed 3.3V output voltage, it can handle a maximum load current of 0.6A. The quiescent current is as low as 200uA, and in theory, it can operate at a frequency of up to 1.2MHz. It provides a stable output voltage, ensuring long - term operation without voltage fluctuations, making it ideal for high - demand applications. Use it to build your own mobile power bank or power your DIY projects. It features a small form factor, stable performance, and a wide voltage range, perfect for a multitude of DIY applications. Applications include powering controller main - boards, DIY current sources, floodlights, toy cars, communication devices, and digital radios. The module has clear interfaces: Vo+ for outputting positive current, Vo - as the ground wire and output port current source reference, Vi - as the ground wire linking to the current source reference, and Vi+ for a 2.5 - 15Vdc power supply input. Specifications include an input voltage of 2.5 - 15Vdc, an output voltage of 3.3V with an accuracy of ±0.1V, a maximum output peak current of 600mA, a full - load output ripple of Vpp < 50mV, a no - load current of 180uA, no switch - off function, an operating temperature range of - 40℃ to +85℃, an operating humidity of 20% - 90% relative humidity without condensation, a storage temperature of - 40℃ to +125℃, a chip - mounting installation method, no isolation, a service life of 30000h, and dimensions of 17×13mm (0.67×0.51inch).

Using this power module is easy. First, connect the input wires. Link Vi+ to a power source with a voltage between 2.5V and 15Vdc, and connect Vi - to the ground wire. For the output, Vo+ will give you the positive current source, and Vo - is the ground wire. You can use it to power different things like controller main - boards or build your own DIY projects. Here are some important notes. Make sure the input voltage doesn't go above 15V. Don't let the load current stay at 600mA or higher for a long time as it can shorten the module's life or even damage it. If you need a high load current, increase the minimum input voltage to keep it working properly. For maintenance, keep the module in a dry place within the recommended temperature and humidity range. If you're not using it for a long time, store it in a safe place within the storage temperature range of - 40℃ to +125℃. With proper use and care, this module can serve you well for up to 30000 hours.
