DI-197 - 65W laptop adapter

DI-197-65W Notebook Adapter

Overview

Design Highlights Very compact, low part count design Reduced internal current limit Eliminates secondary-side current limit circuit Primary-side overvoltage protection (OVP) Eliminates second optocoupler 700 V MOSFET reduces solution cost Low cost (60 V, 20 A) Schottky output diode replaces 100 V, 40 A diode 132 kHz operation reduces transformer size Low MOSFET capacitance enables higher frequency operation without loss of efficiency High energy efficiency Very low no-load input Power: <200 mW @ 265 VAC High Full Load Efficiency: >87% High Average Efficiency: >86% Excellent Transient Load Response Hysteretic Thermal Overload Protection Overload Protection, Automatic Recovery Latching Fault Protection
