MAXIM INTEGRATED / ANALOG DEVICES MAX637ACPA CMOS Inverting Switching Regulator

The MAX637ACP+A is an 8-pin DIP package CMOS inverting switching regulator designed for low power DC-DC conversion. It provides preset or adjustable output, typically -15V, with fine-tuning via external resistors. Integrated low battery detection circuitry enhances functionality. Suitable for low power applications, it requires minimal external components including a diode and output filter capacitor. Operating from 2.3V to 16.5V, it offers 85% efficiency, low supply current of 80µA, and a reference voltage of 1.31V. Its high-accuracy output makes it ideal for power management and portable electronic devices.
