LTC3526LBEDC DC to DC Converter and Switching Regulator Chip 1.755VDC to 1.845VDC/3.2175VDC to 3.3825VDC/4.875VDC to 5.125VDC Output Demonstration Circuit

is an demonstration board that allows the user to quickly evaluate the LTC3526L performance. The LTC3526L is synchronous, fixed frequency step up DC/DC converters with output disconnect. Synchronous rectification enables high efficiency in the low profile DFN package. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. Individual jumpers are provided for selecting several regulated output voltages and a low quiescent current shutdown. Terminals on the board allow easy hook-up to an input supply and output load.
