MAX1680ESA+

The MAX1680ESA+ is a 125mA, frequency selectable, switched capacitor voltage converter in 8 pin SOIC package. It is an inductorless switched-capacitor voltage converter either inverts an input voltage of +2.0V to +5.5V or double it while supplying up to 125mA output current. It has a selectable-frequency option that allows the use of small capacitor of 4.7μF. With their high output current capability, this charge-pump device is suitable replacements for inductor-based regulators which require more expensive external components and additional board space. The device equivalent output resistance (typically 3.5ohm) allows them to deliver as much as 125mA with only a 440mV drop. A shutdown feature reduces quiescent current to less than 1μA. Typical applications include local negative supplies, interface power supplies, op-amp power supplies and MOSFET bias.

• Power efficiency is 90%
• Operating temperature range from -40°C to 85°C
• Selectable switching frequencies of 125KHz/250KHz
