Analog Devices Inc. LTC3670EDDB Demo Board DC1277 is designed to demonstrate the full capacity of the LTC3670 monolithic buck regulator. The LTC3670 is a triple power supply that includes a 400mA synchronous buck regulator and two 150mA Low Drop-Out (LDO) linear regulators. This buck regulator operates from an input supply range of 2.5V to 5.5V that is suitable for single-cell Lithium-ion and Lithium-ion/polymer applications. The Burst Mode operation provides high efficiency in light load and no-load conditions.
