Maxim Integrated Voltage Regulator 20V Negative Polarity Surface Mount SO-8 Package ICL7662CBA+T

Maxim Integrated ICL7662CBA+T is a monolithic charge pump voltage inverter designed for industrial and electronic applications requiring negative voltage supplies. This voltage regulator accepts a positive voltage input ranging from +4.5V up to +20V and inverts it to produce a corresponding negative output voltage between -4.5V and -20V.

This device integrates an oscillator, control circuitry, and four power MOS switches on a single chip, resulting in a compact solution with low quiescent current of only 600μA, thus achieving a typical open circuit conversion efficiency of 99.7%. The regulator requires only two external capacitors, reducing component count and overall system cost.

Encapsulated in a small SO-8 surface mount package measuring 5mm in length, 4mm in width, and 1.5mm in height, the ICL7662CBA+T is suitable for surface mounting on printed circuit boards, offering space savings in compact electronic devices.

This voltage regulator operates reliably up to a maximum temperature of 70°C, ensuring stable performance in a wide range of operating environments.

Applications include negative supply generation for operational amplifiers and other linear circuits, data acquisition systems requiring negative voltages, and supply splitters where the output voltage is half of the input supply voltage.

Operates with input voltage from +4.5V to +20V. Produces negative output voltage from -4.5V to -20V. Low quiescent current of 600μA ensuring high efficiency. Comprehensive integration including oscillator and power MOS switches.
