The Analog Devices Inc./Maxim Integrated MAX634ESA is a versatile buck-boost switching regulator IC designed for step-up and step-down voltage conversion. This adjustable negative output regulator provides up to 150mA of output current with an adjustable output voltage ranging from -2.6V to -20V. It operates with an input voltage range of 2.6V to 16.5V and features a switching frequency between 100Hz and 75kHz. The MAX634ESA is housed in an 8-SOIC package with a 0.154" (3.90mm) width, suitable for surface mount applications. Its buck-boost topology and non-synchronous rectification make it a robust solution for applications in portable electronics, battery-powered devices, and telecommunications equipment. This component operates within an ambient temperature range of -40°C to 85°C.
