CHARGE PUMP DC-TO-DC CONVERTER

FEATURES

GENERAL DESCRIPTION

■ Wide Operating Range ............................. 3V to 18V

■ Increased Output Current .............................. 40mA

■ Pin Compatible with ICL7662/SI7661/TC7660/

LTC1044

The TC7662A is a pin-compatible upgrade to the In-

dustry standard TC7660 charge pump voltage converter. It

converts a +3V to +18V input to a corresponding –3V to

–18V output using only two low-cost capacitors, eliminating

inductors and their associated cost, size and EMI. In addi-

tion to a wider power supply input range (3V to 18V versus

1.5V to 10V for the TC7660), the TC7662A can source

output currents as high as 40mA. The on-board oscillator

operates at a nominal frequency of 12kHz. Operation be-

low 10kHz (for lower supply current applications) is also

possible by connecting an external capacitor from OSC to

ground.

■ No External Diodes Required

■ Low Output Impedance @ I_L= 20mA ....... 40Ω Typ.

■ No Low-Voltage Terminal Required

■ CMOS Construction

ORDERING INFORMATION

Temperature

The TC7662A directly is recommended for designs

requiring greater output current and/or lower input/output

voltage drop. It is available in 8-pin PDIP, and CerDIP

packages in commercial and extended temperature ranges.
