DescriptionThe LM2623-Q1 is a high-efficiency, general-purpose, step-up DC-DC switching regulatorfor automotive systems. The device accepts an input voltage between 0.9 V and 14 V and converts itinto 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 toprogram the output voltage, the operating frequency (300 kHz to 2MHz), and duty cycle(17% to 90%) to optimize performance. The selected values can be fixed or can vary with inputvoltage or input-to-output voltage ratio. The LM2623-Q1 uses a very simple, on/off regulation modeto produce good efficiency and stable operation over a wide operating range. The device normallyregulates by skipping switching cycles when it reaches the regulation limit (pulse frequencymodulation (PFM)).
Refer to Non-Linear Effect andChoosing the Correct C3 Capacitor toresolve any design challenges before board design is finalized.
