1. Introduction
This is a compact and efficient DC-DC step-down power module that supports 7-12V DC input (such as lithium battery packs, adapters, modified power supplies for mobile power banks, etc.), and can provide stable 5V and 3.3V dual-output.The module output end supports both Dupont interface and can be wired by pad, using it is flexible and convenient, very suitable for electronic enthusiasts and developers.The core function of the DC-DC voltage regulator is to stabilize the higher input DC voltage to a lower matched DC voltage (partially supporting wide input range and fixed / adjustable output), it can suppress voltage fluctuations and ripple, partially integrated overvoltage, overcurrent, short-circuit protection, and can provide stable and safe power supply for children's science and technology education products (such as AI brick robots, DIY walkie-talkies), small appliances, Internet of Things devices and other electronic devices, and is a key power conversion component in the electronic system.
