Hot-selling and scarce MAX660CSA CMOS Monolithic Voltage Converter SOP8 spot stock

Product Descriptions

The MAX660 monolithic, charge-pump voltage inverter converts a +1 .5V to +5 .5V input to a corresponding-1.5V  to  -5.5V  output.  Using  only  two  low-cost capacitors, the charge pump’s 100mA output replaces switching regulators, eliminating inductors and their associated cost, size, and EMI . Greater than 90% efficiency over most of its load-current range combined with a typical operating current of only 120µA provides ideal performance for both battery-powered and boardlevel voltage conversion applications. The MAX660 can also double the output voltage of an input power supply or battery, providing +9 .35V at  100mA from a +5V input.

A frequency control (FC) pin selects either 10kHz typ or80kHz typ (40kHz min) operation to optimize capacitor size and quiescent current. The oscillator frequency can also be adjusted with an external capacitor or driven with an external clock. The MAX660 is a pincompatible, high-current upgrade of the ICL7660 . 

The MAX660 is available in both 8-pin DIP and smalloutline packages in commercial, extended, and military temperature ranges.

For 50mA applications, consider the MAX860/MAX861 pin-compatible devices (also available in ultra-smallµMAX packages).
