LMS3635LQRNLRQ1 General Description
With advanced high-speed circuitry, the LMS3655-Q1 excels at regulating an input voltage of 24 V to an output of 3.3 V at a fixed frequency of 400 kHz. Additionally, this regulator can handle continuous load currents of up to 5.5 A, making it ideal for demanding applications. Its frequency foldback architecture allows it to operate efficiently even with as low as a 3.5 V input voltage, with a maximum input voltage tolerance of 36 V and transient tolerance up to 42 V
