Product Summary

The ICL7662EPA is a monolithic charge pump voltage inverter that will convert a positive voltage in the range of +4.5V to +20V to the corresponding negative voltage of -4.5V to -20V. The ICL7662EPA provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. The ICL7662EPA has an oscillator, control circuitry, and 4 power MOS switches on-chip, with the only required external components being two low cost capacitors.

Parametrics

ICL7662EPA absolute maximum ratings: (1)V+TOGND: -0.3V,+22V; (2)Oscillator Input to GND (V- < 12V): -0.3V, V+ + 0.3V; (V+ > 12V): V+ - 12.3V, V+ + 0.3V; (3)Power Dissipation: 300mW; (4)Operating lemperature Ranges: 0 to +70℃; (5)Storage Temperature: -65 to +160℃; (6)Lead Temperature (soldering, 10sec): +300℃.

Features

ICL7662EPA features: (1)+4.5V to +20V Supply to -4.5V to -20V Output; (2)Cascaded Voltage Multiplication (VOUT = -n * V+); (3)99.7% Typical Open Circuit Conversion Efficiency; (4)Requires Only 2 External Capacitors; (5)Pin Compatible with the ICL7660.
