DC / DC Converter For Electric Tuning (3V USE)
   
The TA8126S,TA8126F are DC /DC converter ICs, which are designed for biasing varactor diodes of tuner system. Those items are especially suitable for supplying high voltage (about 15V / 30V) for electric tuning (FM / TV / UHF / AM) system of headphone stereos, radio cassette recorders, or other equipments.
   
Features
● Excellent regulatory capability of output voltage against
    fluctuation of supply voltage, and of ambient temperature.
● Excellent spurious radiation by oscillation of sine wave.
● Output voltage can be switched over to 15V or 30V
    by one−make switch, and is applicable to 10V, too.
● Few external parts.
● Low supply current (at non−load,VCC = 3V, Ta = 25°C)
    ICCQ1 = 2.4mA (typ., VO = 15V mode)
    ICCQ2 = 3.0mA (typ., VO = 30V mode)
● Operating supply voltage range (Ta = 25°C)
    VCC1 (opr) = 1.8~10V, (VO = 15V mode)
    VCC2 (opr) = 2.0~10V, (VO = 30V mode)
