Applications
The EC9206 is a compact PFM step-up DC/DC converter that operates from an input voltage as low as 1.0 Volt. The low start-up input voltage makes EC9206 specially designed for portable devices from one or two cell battery, delivering up to 180mA load current at VIN=1.5V VOUT=3.3V. Typical efficiency for EC9206 is 85% when VIN>=2.0V VOUT=3.
