AX3514 2A Synchronous Step-Down Converter

The AX3514/A/B is a 1.2MHz constant frequency current mode PWM step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The AX3514/A/B also can run at 100.
