General Description

The LP3220 is a 1.5MHz constant frequency current mode PWM step-down converter.

It is ideal for portable equipment which requires very high current up to 1.0A from single-cell Lithium-ion batteries while still achieving over 94% efficiency during peak load conditions.

The LP3220 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 noisy sensitive applications.
