30V Asymmetric Dual N-Channel MOSFET PowerTrench® Power Stage

General Description

This device includes two specialized N-Channel MOSFETs in a dual PQFN package. The switch node has been internally connected to enable easy placement and routing of synchronous buck converters. The control MOSFET (Q1) and synchronousSyncFET (Q2) have been designed to provide optimal power efficiency.
