AX3516 1.
2MHz, 2.
5A Synchronous Step-Down Converter  GENERAL DESCRIPTION The AX3516 is a 1.
2MHz constant frequency current mode PWM step-down converter.
It is ideal for portable equipment requiring very high current up to 2.
5A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions.
The AX3516 also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications.
The AX3516 can supply up to 2.
5A output current from a 2.
6V to 4V input voltage and up to 3A output current from a 4V to 5.
5V input voltage.
The output volt...
