The LM2574M-3.3/NOPB is a voltage regulator manufactured by Texas Instruments. It is part of the DC/DC switching regulators family, which includes a variety of different voltage regulators to regulate the current between two different voltages. The LM2574M-3.3/NOPB is part of the monolithic integrated circuit series and is used to step up or down the current between two different voltages. This regulator is designed for use in automotive, industrial, and lighting applications.

The regulator utilizes Pulse Width Modulation (PWM) control to achieve voltage regulation and high efficiency. The PWM modulator features an internal clock and oscillator which generate a precisely regulated switching frequency. The output current of the regulator can be adjusted with a single resistor connected between the IADJ terminal and ground. The IADJ voltage range is 0 to 1.235V, which allows the user to precisely adjust the output voltage to the desired value.

The LM2574M-3.3/NOPB is designed with a wide input voltage range from 8V to 36V. It can also tolerate an input voltage up to 42V (no load). The regulator also features a low output current ripple, which allows for fewer components and a smaller overall solution size. The maximum power dissipation of the device is 550mW, meaning that higher power loads can be accommodated without an external heat sink.

Overall, the LM2574M-3.3/NOPB is a great choice for any system requiring a voltage regulator for stepping down or boosting an input voltage. With its wide input voltage range and high efficiency, it makes it a great choice for automotive, industrial, and lighting applications. Its low power dissipation allows it to be used in higher power applications without requiring an external heat sink.

As part of the Texas Instruments family of voltage regulators, the LM2574M-3.3/NOPB is an ideal choice for any application requiring precise voltage regulation and efficiency. With its wide input voltage range and adjustable output current, the regulator is well-suited for a variety of automotive, industrial, and lighting applications.
