Boost Converters

Boost converters typically are devices used to increase the voltage from one end, whilst slowing down the current.
How do they work?
The boost converter is able to store energy in its inductor and then simultaneously release it at a higher load voltage than was inputted in the beginning making it very useful in speeding up devices.
Features and benefits:
• Use of inexpensive surface mount inductors (making them very cost effective)
• Low battery detectors included in some models
• High efficiency in all devices
• Consistent peak current control to reduce output ripple
• Electromagnetic interference circuitry
Where might I use one?
• LCD, OLED display supplies
• Mobile phones
• MP3 players
• Haptic displays
• Portable devices like tablets
• PDAs
• Wireless systems
• Bar-code scanners
