CAT661 - High Frequency 100mA CMOS Charge Pump / Inverter/Doubler

Description

The CAT661 is a charge-pump voltage converter.

It can invert a positive input voltage to a negative output.

Only two external capacitors are needed.

Features

  • s Converts V+ to V- or V+ to 2V+ s Low output resistance, 10Ω max. s High power efficiency s Selectable charge pump frequency of 25kHz H GEN FR ALO EE LE A D F R E ETM s Pin-compatible to MAX660, LTC660 with higher frequency operation s Available in 8-pin SOIC andDIP packages s Lead-free, halogen-free package option or 135kHz; optimize capacitor size. s Low quiescent current.
