Quality Control: Learn More
The Microchip Technology LM2575BU is a 1A adjustable output positive buck switching regulator. This device operates with an input voltage range of 4V to 40V, providing a configurable output voltage from 1.23V up to 37V. Featuring an integrated switch, the LM2575BU simplifies power supply design by eliminating the need for external components like Schottky diodes. Its fixed switching frequency of 52kHz allows for the use of smaller inductors and capacitors. The LM2575BU is packaged in a TO-263-5 (D2PAK) surface-mount configuration, suitable for applications in industrial controls, telecommunications, and consumer electronics. This non-synchronous buck converter is designed for efficient step-down voltage conversion.
