Overview
Product Details
Demonstration Circuit 797 is a constant-frequency synchronous Buck-Boost converter using the LTC3440EDD in the 3mm × 3mm DFN-10 package. The input range is from 2.5V to 5.5V, making it ideal for single-cell Lithium-Ion or three-cell NiCd/NiMH battery applications. For 2.7V minimum input voltage, this converter can provide up to 600mA load current. The output voltage is set at 3.3V. A different output voltage in the range of 2.5V to 5.25V can be obtained by changing one of the feedback resistors.
