Beschreibung

Demonstration circuit 2258A features the LT®3048, a Boost DC/DC Converter with integrated Schottky diode and LDO in a 2mm × 2mm DFN package. This demo board is designed to convert a 2.7V to 4.8V input to a 20V output at 10mA to 25mA with low output ripple and noise. The LT3048 allows for the output to be programmed up to 23V. The LT3048 is programmed for 1MHz switching frequency. The LT3048 data sheet gives a complete description of the part, operation, and application information. The data sheet must be read in conjunction with this Quick Start Guide for the demo circuit DC2258A.
