Datasheet Summary
Preliminary Datasheet LP3218
1.5MHz, 1.5A Step-Down Converter
General Description
The LP3218 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 95% efficiency during peak load conditions. The LP3218 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.
The LP3218 can supply up to 2.0A output load current from an input voltage 2.5V to 5.5V and the output voltage can be regulated as low as...
