PowerTrench^®Power Stage

Asymmetric Dual N-Channel MOSFET

Features

General Description

Q1: N-Channel

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

SyncFET (Q2) have been designed to provide optimal power

efficiency.

Max r_DS(on)= 8 mΩ at V_GS= 10 V, I_D= 13 A

Max r_DS(on)= 11 mΩ at V_GS= 4.5 V, I_D= 11 A

Q2: N-Channel

Max r_DS(on)= 2.8 mΩ at V_GS= 10 V, I_D= 23 A

Max r_DS(on)= 3.8 mΩ at V_GS= 4.5 V, I_D= 21 A

Applications

Low inductance packaging shortens rise/fall times, resulting in

Computing

lower switching losses

MOSFET integration enables optimum layout for lower circuit

inductance and reduced switch node ringing
