MAX856CSA Description

Short technical summary and product information.

The MAX856CSA by Analog Devices is a high-efficiency, CMOS step-up DC-DC switching regulator designed for battery-powered systems. It accepts an input voltage as low as 0.8V and can convert it to a higher output voltage, either pin-selectable (3.3V or 5V) or adjustable (2.7V to 6.0V).

 

Key electrical specifications include typical efficiencies greater than 85% at 100mA, a low quiescent current of 25µA, and a shutdown mode current of 1µA. The device features internal MOSFET power transistors enabling high switching frequencies up to 500kHz. It offers switch-current limits of 500mA for the MAX856/MAX857 and 125mA for the MAX858/MAX859, allowing the use of small, low-cost inductors.

 

This regulator is suitable for applications requiring 3.3V to 5V step-up conversion, such as palmtop computers, portable data-collection equipment, personal data communicators, medical instrumentation, and 2-cell or 3-cell battery-operated devices like glucose meters.

 

The MAX856CSA is available in an 8-pin SOIC package and supports surface mount installation. It operates within a temperature range of 0°C to 70°C.
