MAX1973EUB+T is a voltage regulator produced by Maxim Integrated. It is part of the PMIC (Power Management Integrated Circuit) range and specifically belongs to the DC DC Switching Regulators category, and is used in a variety of applications.

The MAX1973EUB+T is a regulated charge-pump DC-DC converter which generates a regulated output voltage in a step-up configuration. It works by converting DC input voltage from Low Voltage Chipset (LVC) output to a higher voltage source, to provide an adequate power supply for applications such as digital cameras, printers, and PDAs.

The MAX1973EUB+T is designed to meet the needs of high efficiency voltage conversion, with typical efficiency values of up to 86% for all combinations of input and output voltages, and with a minimum dropout voltage of 200 mV. The converter also features a low-ripple output and current-limit protection, making it suitable for low-noise and noise-sensitive applications.

The MAX1973EUB+T’s small 8-pin package allows it to be used in space-limited and cost-sensitive applications, as it requires minimal board space, power, and cost. Furthermore, its on-chip 1MHz oscillator provides a frequency of operation which is easily adjustable through the use of an external resistor.

In regards to its application fields, the MAX1973EUB+T is a great asset when using or upgrading existing designs to qualify for Energy Star and IEEE 802.3az compliance. Those fields include, but are not limited to, HDTV receivers, set-top boxes, digital receivers, game systems, LCD monitors, and PDAs.

The maximizing of power efficiency is a key issue for the application of the MAX1973EUB+T. It is particularly useful in devices which are used off of a battery, where power consumption and storage capacity are a major concern. Its low dropout voltage and adjustable clock frequency feature can be used to match the load demand for power with the available power sources.

In addition, its on-chip Soft-Start feature helps to minimize in-rush current and EMI (Electromagnetic Interference) at the time of turn-on, as well as eliminate thermal overshoot. This is achieved by a controlled ramping up of the output voltage over a fixed period of time.

Overall, the use of the MAX1973EUB+T is a cost- and space-efficient way to improve the power efficiency of products and components, which is particularly desirable and encouraged within the areas of high-power consumer electronic and electronic communication devices.
