Asymmetric dual N-channel MOSFET power stage integrates a control MOSFET and a synchronous SyncFET for synchronous buck converter power stages. The device is rated for 25 V drain-to-source operation with ±12 V gate-to-source limits and a -55 °C to 150 °C junction temperature range. Q1 provides 4.7 mΩ maximum on-resistance at 10 V gate drive, while Q2 provides 1.0 mΩ maximum on-resistance at 10 V gate drive. The Power 56 package uses an internally connected switch node to simplify placement and routing and reduce circuit inductance. The part is RoHS compliant and supplied in 3000-unit 13-inch tape-and-reel packaging.
