The MAX1719EUT is a compact, monolithic CMOS charge-pump inverter manufactured by Analog Devices (formerly Maxim Integrated). It is designed to generate a negative voltage supply from a positive input, making it suitable for applications requiring local negative voltage rails.
This device operates with an input voltage range of +1.5V to +5.5V and can deliver a continuous output current of 25mA. The MAX1719/MAX1721 variants operate at a switching frequency of 125kHz, while the MAX1720 operates at 12kHz. The charge pump topology requires minimal external components, typically only two 1µF capacitors for the MAX1719/MAX1721.
Key features include a logic-controlled shutdown with a low 1nA current consumption, high voltage conversion efficiency of 99.9%, and a low quiescent current of 50µA for the MAX1720. These characteristics make it ideal for battery-powered devices and board-level voltage conversion.
The MAX1719EUT is supplied in a small 6-pin SOT-23 package, suitable for surface mount applications where space is a constraint. Its typical applications include generating local negative supplies for analog circuitry, powering small LCD panels, and providing bias for GaAs PA.
