FAQ:

Q: What is the purpose of a DC to DC converter?

A: As the name suggests, a DC to DC Converter is meant to convert one DC voltage into another DC voltage. They are used to increase or decrease the voltage level. DC to DC converters are based on an electronic circuit that uses electronic switching technology.

Q: What is efficiency of DC to DC converter?

A: The average DC/DC converter efficiency varies a lot with battery voltage. At 1.5V the efficiency is more than 87% while at 0.9V it has dropped below 79%. This is measured with an Arduino as load, consuming roughly 5.1mA when the LED is on and 3.6mA when it is off.

Q: Why do we use a DC DC converter?

A: By changing voltage levels-depending on duly cycle it is proportional to D or (1/(1-D)). Switching Safety and match power requirements. Domestic appliances or even in small machines. Pulse Creation etc.

Q: Why do I need a DC/DC converter?

A: DC-to-DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily.
