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.

Key Features

  • Input Voltage Range: 2.5V to 5.5V.
  • Output Voltage Range: 0.61V to VIN.
  • 2.0A Output Current.
  • Low R(DSON) Internal Switches:80mΩ/70mΩ.
  • High Efficiency: Up to 96%.
  • 100% Duty Cycle in Dropout.
  • Low Shutdown Current:.
