The MAX1747EUP+T is a special purpose voltage regulator designed for advanced application levels and performance. It is an improved version of the earlier MAX1747EUP, which provides a wide selection of output voltage ranges and features an independently adjustable programmable UVLO, along with full temperature compensation. The added +T version also provides a temperature sensor output to allow further adjustments to the system power. This makes it suitable for use in a variety of application fields.

Applications

The special purpose voltage regulator, MAX1747EUP+T, can be used in a variety of application fields. It is geared toward three distinct application areas – power management, analog/digital circuits, and sensing – and can be used to improve power efficiency and enhance system performance. Common applications range from providing power to consumer electronics to essential industrial equipment.

• Consumer electronics: Industrial laptops, automotive infotainment systems, wall-mounted lighting controllers
• Industrial appliances and equipment: Automatic washers/dryers, lifts, and construction tools
• Telecom and datacom systems: Servers, routers, and base stations
• Robotics and industrial equipment: Industrial robots, conveyors, and motor control systems
• Power supplies: Laptop, desktop, and server power supplies, as well as other specialty power supplies

Working Principle

The MAX1747EUP+T uses a form of open loop voltage regulation. It uses an internal adjustable reference voltage and a sense resistor to measure the output voltage. As the output voltage falls, the sense resistor reduces the internal reference voltage, which, in turn, increases the amount of output current. This process is repeated until the output voltage is stabilized within the specified range.

The temperature sensor output provides additional information that can be used to fine-tune the output voltage. The output voltage is adjusted according to changes in the temperature of the external environment. This helps to further enhance the accuracy of the voltage regulation.

In addition, the MAX1747EUP+T also uses an adjustable Low Voltage Lock-out (LVLO) circuit to ensure that the output voltage does not exceed a predetermined value. This prevents damage to the circuit by over-voltage, and helps to optimize the power conversion efficiency of the device.

Conclusion

The MAX1747EUP+T is a special purpose voltage regulator designed for advanced application levels and performance. It is well-suited for use in consumer electronics, industrial appliances and equipment, telecom and datacom systems, robotics and industrial equipment, and power supplies. Its open loop voltage regulation process and adjustable reference voltage ensure efficient and stable voltage regulation. Its built-in temperature sensor and adjustable LVLO provide additional protection and flexibility. The MAX1747EUP+T is an ideal choice for those looking for improved performance and power efficiency in their applications.
