Miniature µMAX Package  
The MAX1044 a nd ICL7660 a re monolithic , CMOS  
switched-capacitor voltage converters that invert, dou-  
ble, divide, or multiply a positive input voltage. They are  
pin compatible with the industry-standard ICL7660 and  
LTC1044. Operation is guaranteed from 1.5V to 10V with  
no external diode over the full temperature range. They  
deliver 10mA with a 0.5V output drop. The MAX1044  
has a BOOST pin that raises the oscillator frequency  
above the audio band and reduces external capacitor  
size requirements.

(MAX1044)  
No-Load Supply Current: 200µA Max at 5V  
No External Diode Required for Higher-Voltage  
The MAX1044/ICL7660 combine low quiescent current  
and high efficiency. Oscillator control circuitry and four  
p owe r MOSFET s witc he s a re inc lud e d on-c hip .  
Applications include generating a -5V supply from a  
+5V logic supply to power analog circuitry. For applica-  
tions requiring more power, the MAX660 delivers up to  
100mA with a voltage drop of less than 0.65V.
