The LM25576MHX with Switching Voltage Regulators, manufactured by Texas Instruments, is a 4.5V to 42V, 3A Step-Down DC/DC Switching Regulator available in a 20-HTSSOP package. This device is designed to withstand operating temperatures ranging from -40°C to +125°C, making it suitable for use in automotive, industrial, and other similar applications. It features a wide input voltage range with a low-side current limiting system, and an adjustable output voltage range from 0.8V to 37V. In addition, it offers a low quiescent current operation mode, ePWM to minimize EMI, and it provides outstanding efficiency up to 97% in certain cases. The LM25576MHX also supports Accurate Continuous Conduction Mode (ACCM) and provides a wide range of protection features, such as an adjustable over-temperature protection (OTP) and an internally compensated current sense over-current limiter (LIM).
