TA2018FN Datasheet DC/dc Converter

Manufacturer: Toshiba

Overview: TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2018FN DC / DC Converter For Electric Tuning (1.5V USE) TA2018FN The TA2018FN is a DC / DC converter IC which is developed for biasing variable capacitance diodes of tuner system. It is especially suitable for supplying high voltage (about 14.3V) for digital tuning (FM / TV / AM) system at low power operation.

Key Features

  • Few external parts.
  • Excellent spurious radiation by oscillation of sine wave.
  • Output voltage: VO = 14.3V (typ. ).
  • Excellent regulatory capability of output voltage against fluctuation of supply voltage, and of ambient temperature.
  • Built.
  • in constant current source, it is suitable for digital.
  • tuning system. (ICTL can be controlled by RCTL).
  • Built.
  • in power switch.
  • Low supply current (VCC = 1.2V, Ta = 25°C, IO = 30µA) ICC = 2.1mA (typ. ).
