CAT660EVA

The CAT660 is a charge-pump voltage converter.It will invert a 1.5V to 5.5V input to a -1.5V to -5.5V output.Only two external capacitors are needed.With a guaranteed 100mA output current capability,it can replace a switching regulator and its inductor.Lower EMI is achieved due to the absence of an inductor and can double a voltage supplied from a battery or power supply. Inputs from 2.5V to 5.5V will yield a doubled, 5V to 11V output voltage.The CAT660 replaces the MAX660 and the LTC660.In addition,the CAT660 is pin compatible with the 7660/1044,offering an easy upgrade for applications with 100mA loads.

Features of the CAT660 are:(1)Replaces MAX660 and LTC®660;(2)Converts V+ to V- or V+ to 2V+;(3)Low output resistance, 4typical;(4)High power efficiency;(5)Selectable charge pump frequency:10kHz or 80kHz,Optimize capacitor size;(6)Low quiescent current;(7)Pin-compatible, high-current alternative to 7660/1044;(8)Industrial temperature range;(9)Available in 8-pin SOIC, DIP and 0.8mm thin 8- pad  TDFN packages:Lead-free, halogen-free package option.

The absolute maximum ratings of the CAT660 can be summarized as:(1)V+ to GND:6V;(2)Input Voltage (Pins 1, 6 and 7):-0.3V to (V+ + 0.3V);(3)BOOST/FC and OSC Input Voltage:The least negative of (Out - 0.3V) or (V+ - 6V) to (V+ + 0.3V);(4)Output Short-circuit Duration to GND:1 sec(OUT may be shorted to GND for 1 sec without damage but shorting OUT to V+ should be avoided.);(5)Continuous Power Dissipation (T_A = 70):Plastic DIP is 730mW,SOIC is 500wM and TDFN is 1w;(6)Storage Temperature:-65 to 160;(7)Lead Soldering Temperature (10 sec):300.Note: T_A = Ambient Temperature
