LOW START-UP CURRENT DIRECT CONTROL OF SWITCHING TRANSISTOR COLLECTOR CURRENT PROPORTIONAL TO BASE-CURRENT INPUT REVERSE-GOING LINEAR OVERLOAD CHARACTERISTIC CURVE SIP9 (Plastic Package) ORDER CODE : TDA4601 DESCRIPTION The TDA4601 is a monolithic integrated circuit desi-gned to regulate and control the switching transistor in a switching power supply.
Because of its wide operational range and high vol-tage stability even at high load changes, this IC can be used not only in TV receivers and video recorders but also in power supplies in Hi-Fi sets and active speakers.
