LP3219 - 2A Step-Down Converter

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.

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:.

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 regulated as low as 0.61V.
