Product Description
Texas Instruments LM25574MT/NOPB is a SIMPLE SWITCHER® step-down DC/DC buck converter designed for surface mount applications. It supports an ultra-wide input voltage range from 6V up to 42V and delivers up to 500mA output current with a precise adjustable output voltage down to 1.23V. Its 16-pin TSSOP package with compact dimensions (5mm length × 4.4mm width × 1.2mm depth) offers space-saving on PCB assemblies.
With a maximum operating temperature of 125°C and minimum of -40°C, this buck converter is suitable for demanding industrial and commercial electronic power supply applications. The device features 90% efficiency to minimize power loss and thermal dissipation, benefiting system reliability.
The LM25574MT/NOPB integrates an N-channel MOSFET to simplify design and optimize switching performance. It uses emulated current mode control for fast transient response and allows frequency adjustment between 50kHz and 500kHz via a single resistor. Adjustable soft-start reduces inrush currents during startup.
This buck converter complies with JEDEC and RoHS standards, ensuring environmental compliance and reliability. Typical uses include embedded electronics, telecommunications, industrial controls, instrumentation, and other applications requiring reliable and efficient DC power conversion.
