LM2623MM/NOPB Part Information
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. 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 (300 kHz to 2 MHz) 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). Note: Please read the Non-Linear Effect and Choosing the Correct C3 Capacitor sections so that any challenges with designing with this part can be taken into account before a board design/layout is finalized.
