LM2623 - DC-DC Boost Converter

General Description

The LM2623 is a high-efficiency, general-purpose, step-up DC-DC switching regulator for batterypowered and low input voltage systems.

It accepts an input voltage between 0.8 V and 14 V and converts it into a regulated output voltage between 1.24 V and 14 V.

Key Features

  • 1 Good Efficiency Over a Very Wide Load Range.
  • Very Low Output Voltage Ripple.
  • Up to 2-MHz Switching Frequency.
  • 0.8-V to 14-V Operating Voltage.
  • 1.1-V Start-up Voltage.
  • 1.24-V to 14-V Adjustable Output Voltage.
  • Up to 2-A Load Current at Low Output Voltages.
  • 0.17-Ω Internal MOSFET.
  • Up to 90% Regulator Efficiency.
  • 80-µA Typical Operating Current (Into VDD Pin of Supply).
  • < 2.5-µA Ensured Supply Curre.
