Product Description
The Texas Instruments LM25576MH/NOPB buck converter is a high-performance SIMPLE SWITCHER® step-down regulator designed for surface mount applications. Featuring a wide input voltage range from 6V up to 42V, this device provides an adjustable output voltage as low as 1.225V with a maximum output current of 3A, making it ideal for industrial and electronic power supply designs.
This device includes an integrated N-channel MOSFET and supports operating frequencies adjustable between 50kHz to 500kHz, allowing for optimization of power conversion efficiency, which can reach up to 90%. The high precision 1.5% feedback reference ensures stable voltage output with low ripple.
Packaged in a compact 20-pin TSSOP form factor measuring 6.5mm in length, 4.4mm in width, and 0.9mm in depth, it is suitable for space-constrained printed circuit board designs. The chip is rated for reliable operations within a temperature range from -40°C to 125°C and adheres to JEDEC and RoHS industry standards.
The adjustable soft-start feature provides controlled power-up preventing inrush currents. This buck converter series, including the LM557x and LM2557x, enables robust and flexible power supply designs with minimal external components, suitable for industrial, manufacturing, and laboratory electronic equipment.
Wide input voltage range from 6V to 42V improves compatibility. High efficiency up to 90% reduces power loss and heat dissipation. Adjustable output voltage down to 1.225V supports multiple applications. Integrated N-channel MOSFET reduces component count.
Adjustable frequency between 50kHz and 500kHz enhances flexibility. Compact 20-pin TSSOP package for space-saving designs. Operating temperature range from -40°C to 125°C ensures durability. Compliance with JEDEC and RoHS standards guarantees quality.
This buck converter is ideal for use in power management circuits within industrial and commercial electronics. It supports robust system designs requiring efficient DC/DC voltage regulation. For expanded design options and software support, Texas Instruments provides design tools and documentation via their DesignSpark platform.
