Datasheet
DC / DC Converter For Electric Tuning (1.5V USE)
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.
