DC1053A-E

DC1053A-E demonstration circuits is a high-efficiency synchronous boost converter. It is capable of operating with an input voltage range from 0.8V to 5.5V. The 2X2mm DFN thermally enhanced package with a 1MHz switching frequency 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.

• 4.7µH inductance and burst mode
• 45mV p-p output ripple voltage (burst mode) at VIN = 1.2V, VOUT = 1.8V IOUT = 1mA
