DC1053A-E: 1.8, 3.3, or 5V @ 100mA, 0.8 ~ 5.5V in

Summary

Demonstration circuits1053A-E through 1053AH are high efficiency synchronous boost converters capable of operating with an input voltage range from 0.8V to 5.5V. The 2X2 mm DFN thermally enhanced package with a 1MHz switching frequency (2MHz for -2 versions) and the 550mA internal switches provide a very tiny solution. The LTC3526L family also features output disconnect and the input voltage can be greater or less than the output voltage.

This demonstration circuit allows the user to quickly evaluate the LTC3526L performance. Individual jumpers are provided for selecting several regulated output voltages and a low quiescent current shutdown. Terminals on the board allow easy hookup to an input supply and output load.
