MAX861ISA Description

Short technical summary and product information.

The MAX861ISA is a versatile charge-pump voltage converter designed by Analog Devices / Maxim Integrated. It supports input voltages ranging from +1.5V to +5.5V for inversion or +2.5V to +5.5V for doubling. This device utilizes small capacitors and eliminates the need for inductors, reducing cost, size, and EMI.

 

Key features include three selectable switching frequencies (13kHz, 100kHz, 250kHz) to optimize capacitor size and quiescent current. It provides a 50mA output current with 87% efficiency at 50mA and a low quiescent current of 200µA (for MAX860). The shutdown pin reduces current consumption to less than 1µA.

 

Available in an 8-pin SOIC package, the MAX861ISA is suitable for surface mount applications. Its operating temperature range is -25°C to +85°C. This device is ideal for battery-powered and board-level voltage conversion applications where space and efficiency are critical.

 

Applications include portable computers, medical instruments, interface power supplies, and operational-amplifier power supplies.
