LMC7660 Switched Capacitor Voltage Converter
Checkfor Samples: LMC7660
1FEATURES DESCRIPTIONThe LMC7660isa CMOS voltage converter capable
Operation Over Full Temperature and Voltage of convertinga positive voltagein the rangeof +1.5V
Range withoutan External Diode to +10Vto the corresponding negative voltage of
• Low Supply Current, 200 μA Max −1.5V to −10V. The LMC7660 is a pin-for-pin
Pin-for-pin Replacement for the 7660 replacement for the industry-standard 7660. The
converter features: operation over full temperature
• Wide Operating Range 1.5Vto 10V and voltage range without need foran external diode,
• 97% Voltage Conversion Efficiency low quiescent current, and high power efficiency.
95% Power Conversion Efficiency The LMC7660 usesits built-in oscillatorto switch4
• Easyto Use, Only2 External Components power MOS switches and charge two inexpensive
Extended Temperature Range electrolytic capacitors.
