LP3219 Datasheet (Lowpowersemi) - 2A Step-Down Converter

LP3219, 2A Step-Down Converter

The LP3219 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 2.0A from single-cell Lithium-ion batteries while still achieving over 96% efficiency during peak load conditions.

The LP3219 also can run at 100%
