ماژول رگولاتور DC به DC افزاینده دارای خروجی 1.2A 5V USB

بدل Dc به DC یا DC to DC Converter نوعی مبدل الکترونیکی است که جریان DC را از یک منبع دریافت می‌کند، سپس جریان DC را به صورتی دیگر با سطح ولتاژ بالاتر یعنی مبدل DC به DC افزاینده و یا سطح ولتاژ پایین‌تر یعنی مبدل Dc به DC کاهنده، تغییر می‌دهد. نوعی دیگر از مبدل DC to Dc هستند که ولتاژ را ثابت نگه داشته ولی جریان را تغییر می‌دهند وآن را ماژول رگولاتور DC به DC افزاینده می نامند. ماژول مبدل تقویت کننده DC-DC 1.2A (2.0-5V) USB، دارای ورودی 2 تا 5 ولت DC، خروجی ثابت ولتاژ 5V DC ، جریان ورودی 1000mA با دو باتری AA، یک منبع تغذیه دارای یک باتری لیتیومی با خروجی جریان 1200mA مناسب برای تغذیه ی گوشی های تلفن همراه، دوربین ها و تغذیه تجهیرات دیجیتالی سازگار می باشد.
با استفاده از پورت USB تعبیه شده بر روی ماژول، میتوان از این مبدل برای انواع تجهیزات الکترونیکی استفاده کرد و همچنین این ماژول دارای اندازه کوچکی است که می توان آن را در دستگاه های کوچک به کار گرفت.
این ماژول دارای ضریب بازدهی حداکثری 90 درصد می باشد.

Description:
A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor, or the two in combination. To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter). A process that changes one DC voltage to a different DC voltage is called DC to DC conversion. A boost converter is a DC to DC converter with an output voltage greater than the source voltage. A boost converter is sometimes called a step-up converter since it "steps up" the source voltage.
Most DC-to-DC converters are designed to move power in only one direction, from dedicated input to output. However, all switching regulator topologies can be made bi-directionally and able to move power in either direction by replacing all diodes with independently controlled active rectification. A bidirectional converter is useful, for example, in applications requiring regenerative braking of vehicles, where power is supplied to the wheels while driving, but supplied by the wheels when braking.
DC to DC converter is used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage). Additionally, the battery voltage declines as its stored energy are drained. Switched DC to DC converters offer a method to increase the voltage from a partially lowered battery voltage thereby saving space instead of using multiple batteries to accomplish the same thing.
Most DC to DC converter circuits also regulates the output voltage. Some exceptions include high-efficiency LED power sources, which are a kind of DC to DC converter that regulates the current through the LEDs, and simple charge pumps which double or triple the output voltage.
