TC7662B  
CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER  
FEATURES  
GENERAL DESCRIPTION  
Wide Operating Voltage Range: 1.5V to 15V  
Boost Pin (Pin 1) for Higher Switching Frequency  
High Power Efficiency is 96%  
Easy to Use – Requires Only 2 External Non-Critical  
Passive Components  
The TC7662B is a pin-compatible upgrade to the Indus-  
try standard TC7660 charge pump voltage converter. It  
converts a +1.5V to +15V input to a corresponding – 1.5 to  
– 15V output using only two low-cost capacitors, eliminating  
inductors and their associated cost, size and EMI.  
The on-board oscillator operates at a nominal fre-  
quency of 10kHz. Frequency is increased to 35kHz when  
pin 1 is connected to V+, allowing the use of smaller external  
capacitors.Operationbelow10kHz(forlowersupplycurrent  
applications) is also possible by connecting an external  
capacitor from OSC to ground (with pin 1 open).  
Improved Direct Replacement for Industry Stan-  
dard ICL7660 and Other Second Source Devices  
APPLICATIONS  
Simple Conversion of +5V to ±5V Supplies  
Voltage Multiplication VOUT = ±nVIN  
Negative Supplies for Data Acquisition Systems  
and Instrumentation  
The TC7662B is available in both 8-pin DIP and 8-pin  
small outline (SO) packages in commercial and extended  
temperature ranges.
