Description
Demonstration circuit 2120A features the LT3048-15, 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 15V output
at 19mA to 35mA with low output ripple and noise. The
LT3048-15 is programmed for 2MHz switching frequency.
This demonstration board can be used to evaluate other
fixed output voltage versions of the LT3048.
