LM5575MH General Description

LM5575MH is a step-down voltage regulator manufactured by Texas Instruments. It is a high-performance and adjustable switching regulator designed to deliver up to 1A of output current with an input voltage range of 4.5V to 75V. The LM5575MH operates at a fixed frequency of 200 kHz, which helps to minimize the size of external components. It features an adjustable output voltage range from 1.23V to 37V, making it versatile for a variety of applications. The device has integrated protection features such as thermal shutdown, short-circuit protection, and overcurrent protection, ensuring reliable operation and safeguarding against damage under fault conditions. Additionally, the LM5575MH offers high efficiency with up to 83% efficiency at full load.The LM5575MH comes in a 8-pin power SOIC package, making it easy to use in space-constrained applications.
