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.
Features
