LTC3649 Hold-Up Circuit Using a Buck Regulator with Vin Boost Capabilities
Aug 18th 2016
One very important, but not the much known future of LTC®3649 is ability provide hold-up time for critical systems at power outage. Usual solution for providing energy during hold-up time is to use dedicated controllers and storage capacitors. Such approach is absolutely adequate if high levels of energy needed during ...
Low Voltage Power Supplies
Jun 9th 2016
In this video, Linear Technology Co-founder and CTO Bob Dobkin discusses low voltage power supplies less than half a volt. Most of today's power supplies have a reference of 0.6 volts, which means the output voltage must be greater than 0.6 volts. Several years ago, Linear Technology pioneered a new type of current source ...
