1 / 12 page  LMC7660 Switched Capacitor Voltage Converter General Description The LMC7660 is a CMOS voltage converter capable of con- verting a positive voltage in the range of +1.5V to +10V to the corresponding negative voltage of −1.5V to −10V. The LMC7660 is a pin-for-pin replacement for the industry-standard 7660. The converter features: operation over full temperature and voltage range without need for an external diode, low quiescent current, and high power effi- ciency. The LMC7660 uses its built-in oscillator to switch 4 power MOS switches and charge two inexpensive electrolytic ca- pacitors. Features n Operation over full temperature and voltage range without an external diode n Low supply current, 200 µA max n Pin-for-pin replacement for the 7660 n Wide operating range 1.5V to 10V n 97% Voltage Conversion Efficiency n 95% Power Conversion Efficiency n Easy to use, only 2 external components n Extended temperature range n Narrow SO-8 Package Block Diagram Pin Configuration Ordering Information Package Temperature Range NSC Drawing Industrial −40˚C to +85˚C 8-Lead Molded DIP LMC7660IN N08E 8-Lead Molded Small Outline LMC7660IM M08A DS009136-1 DS009136-2 April 1997 © 1997 National Semiconductor Corporation DS009136 www.national.com |
