Features
Q1: N-Channel Max rDS(on) = 8 mΩ at VGS = 10 V, ID = 13 A Max rDS(on) = 11 mΩ at VGS = 4.5 V, ID = 11 A
Q2: N-Channel Max rDS(on) = 1.8 mΩ at VGS = 10 V, ID = 30 A Max rDS(on) = 2.2 mΩ at VGS = 4.5 V, ID = 27 A Low inductance packaging shortens rise/fall times, resulting in
lower switching losses
MOSFET integration enables optimum layout for lower circuit inductance and reduced switch node ringing
RoHS Compliant

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 synchronous SyncFETTM (Q2) have been designed to provide optimal power efficiency.
