LM2642MTC General Description

Meet the LM2642MTC, an advanced step-down switching regulator from Texas Instruments engineered for high efficiency and reliability. With an input voltage range of 4.5V to 42V, this regulator is well-suited for a variety of applications, including automotive and industrial settings. Capable of delivering up to 2A of output current with an efficiency of up to 95%, the LM2642MTC stands out for its performance. Employing a voltage mode control topology, this regulator ensures stable operation, while adjustable frequency and soft-start features provide enhanced flexibility and reliability. Safety features such as overcurrent protection, thermal shutdown, and undervoltage lockout further guarantee secure operation. Housed in a compact TSSOP-16 package, the LM2642MTC is the perfect choice for space-constrained designs
