DC/DC CONVERTER FOR ELECTRIC TUNING

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. · Built−in constant current source, it is suitable for digital tuning system. (ICTL can be controlled by RCTL) · Output voltage VO = 15.5V (typ.) Weight: 0.09g (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 Block Diagram TA8198F ※ Handle with care to prevent devices from deterioration by static electricity. 1 2002-10-30 TA8198F Terminal Explanation Terminal Voltage: Typical Terminal Voltage with Test Circuit (VCC = 3V, Ta = 25°C) Terminal Terminal No. Name Function Internal Circuit Terminal Voltage (V) 1 DET ― 2 VO Boosted output (voltage double rectifier) 15.5 5 CF 1.4 3 ICTL 4 CTL Constant current source output (for digital tuning) VO supplies this circuit with power source. In case that this circuit isn't used, the ICTL terminal .
