MAX1901ETJ+T

Introduction

MAX1901ETJ+T is a multi-bottom switched capacitor (MSC) integrated circuit, designed for special purpose voltage regulation applications. It is primarily used to regulate output voltage from a wide input voltage range (5V to 8V). It uses an optimized, non-linear topology for on-chip switching converter regulation with tightly regulated output, high efficiency, fast transient response, and wide input dynamic range.

Application field

MAX1901ETJ+T is designed for use in applications that require high dynamics as well as a high output accuracy. Examples of these dynamic applications include: mobile devices, battery-operated systems, automotive systems, consumer electronics and industrial control applications. Additionally, MAX1901ETJ+T can also be used in high-power applications such as LED lighting, high-power audio amplifiers, motor control applications, and many other scenarios where the output must be tightly regulated and the input voltage range is rather wide.

Working principle

The working principle of MAX1901ETJ+T is based on a non-linear, switch-mode regulation loop. Its operation can be divided into two unique sections: the voltage regulation section, and the current regulation section. In the voltage regulation section, the input voltage is compared to a reference voltage and the difference is used to generate a voltage-error signal. This voltage-error signal is then used to control a switching converter circuit that regulates the output voltage by synchronizing the energy stored in the output inductor. At the same time, the current regulation section is responsible for consuming the excess energy that is produced by the voltage regulation section before it is dissipated inside the switching converter circuit.

Conclusion

MAX1901ETJ+T is a powerful and versatile integrated circuit, designed for special purpose voltage regulation applications. It utilizes a non-linear, switch-mode regulation loop that efficiently regulates output voltage over a wide input voltage range. It is ideal for applications such as mobile devices, battery-operated systems, automotive systems, consumer electronics and industrial control applications, as well as high-power applications such as LED lighting and high-power audio amplifiers.
