AON7826
20V Dual N-Channel MOSFET
General Description
The AON7826 is designed to provide a high efficiency
synchronous buck power stage with optimal layout and
board space utilization. It includes two low RDS (ON)
MOSFETs in a dual DFN3x3 package. The AON7826 is
well suited for use in compact DC/DC converter
applications.
