Analog Devices Inc./Maxim Integrated MAX861ISA is a charge pump switching regulator IC designed for applications requiring efficient voltage inversion or doubling. This device offers a fixed output of either -Vin or 2Vin, delivering up to 50mA. With selectable switching frequencies of 13kHz, 100kHz, and 250kHz, designers can optimize for efficiency or size. The MAX861ISA operates from a wide input voltage range of 1.5V to 5.5V and is housed in an 8-SOIC package suitable for surface mounting. Its integrated charge pump topology eliminates the need for inductors, making it ideal for space-constrained designs in portable electronics and power management systems. The operating temperature range is -25°C to 85°C.
