Beschreibung

The SGM64A00 is a wide input voltage range synchronous Buck controller, supporting an input voltage range of 6.5V to 100V. The minimum high-side MOSFET on-time of 40ns effectively supports low duty cycle applications. The device can be directly applied to industrial-standard 48V high-voltage DC power supply systems, enabling step-down conversion to low-voltage power rails (e.g., 5V/12V). The SGM64A00 is suitable for applications with stringent requirements on input voltage fluctuations, such as industrial power supplies and communication base stations.
