Overview
FDS6984AS J May 2008 FDS6984AS General Description Dual Notebook Power Supply N-Channel PowerTrench® SyncFET™ Features • Q2: Optimized to minimize conduction losses Includes SyncFET Schottky diode RDS(on) max= 20 mΩ @ VGS = 10V RDS(on) max= 28 mΩ @ VGS = 4.
5V • Q1: Optimized for low switching losses Low gate charge (8nC typical) RDS(on) max= 31 mΩ @ VGS = 10V RDS(on) max= 40 mΩ @ VGS = 4.
5V • RoHS Compliant The FDS6 984AS is designed t o replace t wo single SO-8 MOS FETs and Schottk y diode in s ynchronous DC:DC p ower supplies that prov ide various perip heral voltages for not ebook computer s and oth er battery powered electro nic devices .
FDS6984AS contains tw o unique 30V, N-channel, logic level, PowerT rench MOSFETs designed to maximi ze pow er conversion efficiency.
The high-side sw itch ( Q1) is designed w ith sp ecific emphasis on reducing sw itching losse s w hile th e low side sw itch (Q2 ) is optimized t o reduce condu ction losses.
Q2 also includes a pate nted combination of a MOSFET mono lithically integrat ed w ith a Schottk y diode.
