Texas Instruments LM25574 SIMPLE SWITCHER? 42V, 0.5A Step-Down Switching Regulator LM25574MTX/NOPB

The LM25574MTX/NOPB is a step-down switching regulator designed for applications requiring a robust power supply. It operates with an input voltage range of 6V to 42V and provides a continuous output current of 0.5A. The device features an integrated 750-m,Ѷ N-Channel MOSFET, which enhances efficiency and reduces the need for external components. The output voltage is adjustable down to 1.225V, allowing for flexibility in design. This regulator employs an emulated current mode control architecture, which ensures good line regulation and a fast load transient response. The operating frequency can be adjusted between 50 kHz and 1 MHz using a single resistor, enabling optimization for size and efficiency. Additionally, it includes features such as cycle-by-cycle current limit, short-circuit protection, thermal shutdown, and remote shutdown capabilities, ensuring reliable operation in various conditions. The LM25574MTX/NOPB is housed in a TSSOP-16 package, making it suitable for space-constrained applications. It is supported by WEBENCH¬Æ design tools, facilitating custom design and implementation. This product is recommended for industrial applications and is compliant with RoHS standards.
