TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8198F
DC / DC Converter For Electric Tuning (3V USE)
The TA8198F is a DC / DC converter IC which is developed for
biasing varactor diodes of tuner system.
It is especially suitable for supplying high voltage (about 15.5V)
for digital tuning (FM / TV / AM) system of headphone stereos,
radio cassette recorders, or other equipments.
Features
Few external parts.
Excellent spurious radiation by oscillation of sine wave.
Builtin constant current source, it is suitable for digital
tuning system. (ICTL can be controlled by RCTL)
Output voltage VO = 15.5V (typ.)
Excellent regulatory capability of output voltage against
fluctuation of supply voltage, and of ambient temperature.
Builtin power switch
Low supply current (at nonload, VCC = 3V, Ta = 25°C) ICCQ = 2.4mA (typ.)
Operating supply voltage range (Ta = 25°C) VCC (opr) = 1.8~10V
