TA8126S / F
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8126S,TA8126F
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)
