Product Overview

The LM2623AMM/NOPB is a general-purpose gated-oscillator-based step-up DC-to-DC Boost Converter for battery-powered and low input voltage systems. It accepts an input voltage between 0.8 and 14V and converts it into a regulated output voltage between 1.24 and 14V. Efficiencies up to 90% are achievable with the LM2623. In order to adapt to a number of applications, the LM2623 allows the designer to vary the output voltage, the operating frequency (300kHz to 2MHz) and duty cycle (17 to 90%) to optimize the part's performance. The selected values can be fixed or can vary with battery voltage or input to output voltage ratio. The LM2623 uses a very simple, on/off regulation mode to produce good efficiency and stable operation over a wide operating range. It normally regulates by skipping switching cycles when it reaches the regulation limit (pulse frequency modulation).
  • Good efficiency over a very wide load range
  • Very low output voltage ripple
  • 1.1V Startup voltage
  • Up to 2A load current at low output voltage
  • 0.17Ω Internal MOSFET
  • Up to 90% regulator efficiency
  • 80µA Typical operating current (into VDD pin of supply)
  • <2.5µA Ensured supply current in shutdown
  • Green product and no Sb/Br
