The MQ7221BK Power Modules are non-isolated dc-dc converters that operate over a wide input voltage range of 4.5Vdc to 20Vdc and provide a precisely (2%) regulated dc output. Such a module is suitable to applications with unregulated 12V power supply bus or low-cost ac-wall adapter, which have two and more lower voltages with each current not too high. The modules have a maximum output current rating of 3A for each output at a typical full-load efficiency over 91%. Standard features include remote on/off with positive logic and output voltage wide trim, over-current protection et
