s s s s s 99% Voltage Conversion Efficiency 85% Power Conversion Efficiency Wide Voltage Range ......................... +2.0V to +5.5V Only 4 External Capacitors Required Space Saving 8-Pin SOIC Design GENERAL DESCRIPTION
Common applications include ±10V from a single +5V logic supply, and ±6V from a +3V lithium battery. Low output source impedances (typically 150Ω) provides maximum output currents of 10mA for each output. Typical power conversion efficiency is 85%. High efficiency, small installed size and low cost make the TCM680 suitable for a wide variety of applications that need both positive and negative power supplies derived from a single input voltage. 2 3 4 5 6 7 APPLICATIONS
