The SGM61280 is a high efficiency and miniature size synchronous Buck converter for wide input voltage applications.
The SGM61280, 8A synchronous Buck converter with integrated low RDSON MOSFET switches, provides SGM61280-3.3 and SGM61280-5.1 efficient fixed output voltage version. The device uses constant on-time (COT) control for fast transient response and supports input voltage range from 4.5V to 23V for the SGM61280-3.3, and 5.1V to 23V for the SGM61280-5.1.
The SGM61280 is available in a space-saving Green UTQFN-3×3-12AL package.
