MT4914
Dual N-Ch PowerTrench SyncFET™
General Description
The MT4914 is designed to replace two single SO8 MOSFETs and
Schottky diode in synchronous DC:DC power supplies that provide various peripheral voltages for notebook computers and other battery powered electronic devices. MT4914 contains two unique 30V, 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 MOS-TECH’s monolithic SyncFET technology.
