The MAX1720EUT from Analog Devices (formerly Maxim Integrated) is a compact, monolithic CMOS charge-pump inverter designed for efficient voltage conversion. It operates with an input voltage range of +1.5V to +5.5V and can supply a continuous output current of 25mA. This device is suitable for applications requiring a local negative supply from a positive source, such as small LCD panels, GaAs PA bias supplies, and battery-operated equipment.
The MAX1720EUT features logic-controlled shutdown with a low shutdown current of 1nA, and a quiescent current of 50µA. It operates at a switching frequency of 12kHz and requires minimal external components, typically only two 1µF capacitors. The device is housed in a small 6-pin SOT-23 package, making it ideal for space-constrained board designs. Its high efficiency and small footprint contribute to its suitability for both battery-powered and board-level voltage conversion needs.
Key electrical characteristics include a wide input voltage range and a fixed output type. The topology is a charge pump, and it does not utilize a synchronous rectifier. The operating temperature range is -40°C to +85°C, ensuring reliable performance in various environments. The device is surface-mount compatible, facilitating integration into automated manufacturing processes.
