Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX1595 charge-pump regulator generates either 3.3V or 5V from a 1.8V to 5.5V input. The unique control architecture allows the regulator to step up or step down the input voltage to maintain output regulation.The 1MHz switching frequency, combined with a unique control scheme, allows the use of a ceramic capacitor as small as 1F for 125mA of output current.

The complete regulator requires three external capacitors-no inductor is needed. The MAX1595 is specifically
designed to serve as a high-power, highefficiency auxiliary supply in applications that demand a compact design. The MAX1595 is offered in spacesaving 8-pin MAX and high-power 12-pin thin QFN packages.
