MOSFET – Dual, N-Channel, POWERTRENCH), SyncFETt
FDS6900AS, FDS6900AS-G
General Description The FDS6900AS is designed to replace two single SO−8 MOSFETs
and Schottky diode in synchronous dc−dc power supplies that provide various peripheral voltages for notebook computers and other battery powered electronic devices. FDS6900AS contains two unique 30 V, N−channel, logic level, POWERTRENCH MOSFETs designed to maximize power conversion efficiency.
The high−side switch (Q1) is designed with specific emphasis on reducing switching losses while the lowside switch (Q2) is optimized to reduce conduction losses. Q2 also includes an integrated Schottky diode using onsemi’s monolithic SyncFET technology.
