Description
AI
The LM2623-Q1 is a high-efficiency, general-purpose, step-up DC-DC switching regulator for automotive systems. The device accepts an input voltage between 0.9 V and 14 V and converts it into a regulated output voltage between 1.24 V and 14 V.
In order to adapt to a number of applications, the LM2623-Q1 allows the designer to program the output voltage, the operating frequency (300 kHz to 2 MHz), and duty cycle (17% to 90%) to optimize performance. The selected values can be fixed or can vary with input voltage or input-to-output voltage ratio. The LM2623-Q1 uses a very simple, on/off regulation mode to produce good efficiency and stable operation over a wide operating range. The device normally regulates by skipping switching cycles when it reaches the regulation limit (pulse frequency modulation (PFM)).
