MAXIM INTEGRATED / ANALOG DEVICES MAX868EUBT Inverting Charge Pump
The MAX868EUB+T is a regulated, adjustable inverting charge pump in a 10-pin µMAX package. It provides a cost-effective, compact solution for generating a negative voltage up to -2 times the positive input voltage from 1.8V to 5.5V. Using pulse frequency modulation (PFM), it switches its internal 450 kHz oscillator on and off to efficiently maintain output regulation, especially at light loads, without sacrificing performance at higher currents up to 30mA. It requires only four small capacitors and two resistors, making it ideal for small LCD panels, cordless phones, camcorders, and portable electronics. Operating from -40°C to 85°C with low shutdown current, it is suitable for battery-operated applications requiring reliable and efficient negative voltage generation.
