Datasheet Summary
Preliminary Datasheet LP3219
1.5MHz, 2A Step-Down Converter
General Description
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% 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 LP3219 can supply up to 2.0A output load current from at VIN = 3V and has an input voltage 2.5V to 5.5V and the output voltage can be...
