Here is my youtube video on this subject:
ICStation.com is offering this small boost converter module. The power supply module is straight forward. There is a 2.8 to 5.5 V DC input and the module outputs +12 V and -12 V DC dual power supply voltage with a current rating of maximum 30 mA. Off course the current output is low but sometimes it suits in many situations where one is looking forward for a small boost converter having such voltage capability and small size. The typical use can be as most operation amplifiers, Digital to analogue and analogue to digital converters. The other used one can think about. The beauty of the converter is its small size about an inch and very low price. There is special discount of 30% for people who are about to purchase such a module with my reference from ICstation.com. For discount coupon just visit my youtube channel and there you will get all details in the description section. There on my channel I describe it in the video and showed all details and testing of the module. Please watch my video to get complete understanding of the module.
Here is a little detail from the website:
Product Introduction:
1.Input Voltage Range:2.8V-5.5V
2.Output Voltage:+/-12V (V +:+12V;V-:-12V)
3.Output Current:+12V stable output current capability of 50mA,-12V stable output current capability 30mA,almost meet all ADC, DAC and amplifier applications
4.Size:2.4*1.2cm
5.Application:can be used as ADC,DAC or amplifier,dual power supply
Note: The -12V supply is lower 0.4-0.6V than the + 12V supply because of the the partial voltage of the diode.
Please do not connect high-power load for this module is a small current.
