TA8126F DC/DC CONVERTER FOR ELECTRIC TUNING

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 / U.

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) Block Diagram Weight SIP9−P−2.54C: 0.72g (typ.).
