FAN23SV70AMPX

FAN23SV70AMPX Description

The FAN23SV70AMPX from onsemi is a high-performance, adjustable synchronous buck regulator designed for demanding power management applications. This 20A output current DC-DC converter operates with an input voltage range of 7V to 24V, delivering an adjustable output voltage from 0.6V to 5.5V. Its 200kHz to 1MHz switching frequency allows for flexibility in design, balancing efficiency and component size. Packaged in a 34-pin QFN and available in Tape & Reel (TR), this obsolete but RoHS3-compliant regulator is suited for high-density PCB layouts. The synchronous rectification topology enhances efficiency, making it ideal for applications requiring high current with minimal losses.
