Overview
TK11822/11823 DC-DC CONVERTER FEATURES s s s s s s Very Low Noise Low Operating Voltage Range Few External Components Wide Supply Voltage Range Sinewave Oscillation Selectable Output Voltages APPLICATIONS s s s s s s Headphone Stereos Pagers Mobile Wireless Equipment Electronic Diaries Other Battery-powered Equipment LCD TV's DESCRIPTION The TK11822M and TK11823M are booster-type DC-DC converters developed principally for use as power supplies to drive variable capacitance diodes.
Both products are low power output types, suitable for operation at low voltages.
To suppress AM band noise, they use high frequency sine wave oscillation.
Both products are available in two output voltages, allowing the user to select the most efficient voltage for the equipment.
The products have built-in rectifier diodes and small packages, contributing to equipment miniaturization.
