TA2018FN Description
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2018FN DC / DC Converter For Electric Tuning (1.5V USE) TA2018FN The TA2018FN is a DC / DC converter IC which is developed for biasing variable capacitance diodes of tuner system. It is especially suitable for supplying high voltage (about 14.3V) for digital tuning (FM / TV / AM) system at low power operation.
