The LM3488MM is an automotive-grade DC-DC switching controller designed for boost, SEPIC, and flyback converter applications. It is AEC-Q100 qualified, ensuring reliability in automotive environments. The device features an 8-lead VSSOP package and includes an internal push-pull driver capable of delivering a peak current of 1 A. Key specifications include a wide supply voltage range from 2.97 V to 40 V, adjustable switching frequency from 100 kHz to 1 MHz, and an internal reference accuracy of ±1.5% over temperature. The LM3488MM incorporates essential protection features such as current limit, thermal shutdown, and undervoltage lockout with hysteresis. It also supports current mode operation for improved transient response and allows for output current programming with an external resistor. The device's internal soft-start function limits inrush current during startup, and its power-saving shutdown mode reduces supply current to 5 µA. This controller is suitable for various applications, including automotive start-stop systems, portable audio devices, and offline power supplies.
