TDA4601
TDA4601 is SWITCH-MODE POWER SUPPLY CONTROLLER manufactured by SGS-THOMSON.
- Part of the TDA4601-SGS comparator family.
- Part of the TDA4601-SGS comparator family.
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.
