Note 1: The maximum input voltage may be exceeded if the maximum input current and power dissipation specifications are observed.

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 MAX610/MAX611/MAX612 AC-to-DC power converters reduce the component count, size, and weight of 1/4 watt power supplies, thus minimizing the overall cost and simplifying designs. With an 8V_RMS input voltage, the MAX610 needs only a single filter capacitor to make a complete 5V, 50mA power supply. With the addition of a current-limiting resistor and a current-limiting capacitor, the MAX610 connects directly to the 110VAC or 220VAC power line to make a minimum component count 110/220VAC to 5VDC power supply.

The MAX612 in the MAX610 family differ in three respects: full- or half-wave rectification, 12V or 18V zener voltage, and the assignment of pin 4 to the function of setting the output voltage or setting the time delay. The MAX610 has a full-wave rectifier, a 12V zener, and the output voltage is either the internally preset +5V or user adjustable from +1.3V to +9V. The MAX611 has a half-wave rectifier, a 12V zener, a fixed +5V output, and pin 4 controls the time delay of the reset output. The MAX612 has a full-wave rectifier, an 18V zener, and the output voltage is either the internally preset +5V or user adjustable from +1.3V to +15V.

The low-cost MAX612 is ideal for applications where the size, weight, and component count of 1/4 watt power supplies must be reduced. Reliable power-up reset and over/undervoltage detection makes MAX612 well suited for microprocessor-based controllers.
