LMC7660
www.ti.com SNOSBZ9C – APRIL 1997 – REVISED APRIL 2013 LMC7660 Switched Capacitor Voltage Converter
Check for Samples: LMC7660 FEATURES DESCRIPTION The LMC7660 is a CMOS voltage converter capable
of converting 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 efficiency. 1 2 Operation Over Full Temperature and Voltage
Range without an External Diode
Low Supply Current, 200 ОјA Max
Pin-for-pin Replacement for the 7660
Wide Operating Range 1.5V to 10V
97% Voltage Conversion Efficiency
95% Power Conversion Efficiency
Easy to Use, Only 2 External Components
Extended Temperature Range The LMC7660 uses its built-in oscillator to switch 4
power MOS switches and charge two inexpensive
electrolytic capacitors. Block Diagram Pin Configuration 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
