The MAX858CSA is a high-efficiency, CMOS step-up DC-DC switching regulator designed for battery-powered systems. It accepts an input voltage range of 0.8V to 6.0V and can convert it to a higher output voltage, either fixed at 3.3V or 5V, or adjustable. The device boasts typical efficiencies greater than 85% and a low quiescent current of 25µA, maximizing battery life.
Key electrical specifications include a 125mA switch-current limit, which allows for the use of small, low-cost inductors, and a switching frequency of up to 500kHz. The operating temperature range is 0°C to 70°C (TA).
This regulator is suitable for applications requiring 3.3V to 5V step-up conversion, such as palmtop computers, portable data-collection equipment, and 2-cell or 3-cell battery-operated devices. It is available in an 8-pin SOIC package and is surface-mount compatible.
