3.0 MHz, 300 MA, DC-to-DC Boost Converter
The PCA9412 and PCA9412A are highly efficient 3.0 MHz, 300 mA, step-up DC-to-DC converters. They convert input voltages from 2.5 V to 5.25 V to a fixed output voltage of 5.4 V.
These devices are optimized for battery-powered applications. High efficiency of up to 94 % enables an extended battery life in all portable designs. Step-up operation at a switching frequency of 3 MHz allows using 1 µH inductor or smaller.
