TA8198F Overview
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.
TA8198F Key Features
- Few external parts
- Excellent spurious radiation by oscillation of sine wave
- Built-in 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
- Built-in power switch
- Low supply current (at non-load, VCC = 3V, Ta = 25°C) ICCQ = 2.4mA (typ.)
- Operating supply voltage range (Ta = 25°C) VCC (opr) = 1.8~10V
- VCE1 (sat))
