CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER

FEATURES

GENERAL DESCRIPTION

■ Converts +5V Logic Supply to ±5V System

■ Wide Input Voltage Range ....................1.5V to 12V

■ Efficient Voltage Conversion......................... 99.9%

■ Excellent Power Efficiency ............................... 98%

■ Low Power Consumption ............ 80µA @ V_IN= 5V

■ Low Cost and Easy to Use

The TC1044S is a pin-compatible upgrade to the Indus-

try standard TC7660 charge pump voltage converter. It

converts a +1.5V to +12V input to a corresponding –1.5V

to –12V output using only two low cost capacitors, eliminat-

ing inductors and their associated cost, size and EMI.

Added features include an extended supply range to 12V,

and a frequency boost pin for higher operating frequency,

allowing the use of smaller external capacitors.

Theon-boardoscillatoroperatesatanominalfrequency

of 10kHz. Frequency is increased to 45kHz when pin 1 is

connected to V⁺. Operation below 10kHz (for lower supply

current applications) is possible by connecting an external

capacitor from OSC to ground (with pin 1 open).

— Only Two External Capacitors Required

■ RS-232 Negative Power Supply

■ Available in 8-Pin Small Outline (SOIC) and 8-Pin

Plastic DIP Packages

■ Improved ESD Protection ..................... Up to 10kV

■ No External Diode Required for High Voltage

Operation

■ Frequency Boost Raises F_OSCto 45kHz

The TC1044S is available in both 8-pin DIP and

8-pin small outline (SOIC) packages in commercial and

extended temperature ranges.
