General Description

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

TM

SyncFET

(Q2) have been designed to provide optimal power

efficiency.
