Introduction

The MAX15059AETE+T is a special purpose voltage regulator integrated module (PMIC) for low-noise resistive, high-voltage applications. It consists of an integrated 1A (average) fixed-frequency current-mode regulator and an adjustable VOUT built-in reference with an adjustable output voltage. The MAX15059AETE+T operates from 1V to 200V and is suitable for use in systems that require higher noise immunity and improved power supply design. Its integrated design, which combines an integrated regulator and reference, makes it suitable for applications that require higher noise immunity and improved power supply design.

Features

The MAX15059AETE+T is capable of providing up to 1A of continuous output current with a typical 3V to 100V input voltage range and a 0.6V to 8V output voltage range. It has low output voltage ripple of less than 2mV and high peak efficiency of up to 90% with a constant frequency current mode operation. It also has a built-in over-temperature shutdown for safe operation, a soft start for better current limiting, and an adjustable VOUT reference with an adjustable output voltage. Furthermore, the MAX15059AETE+T is compliant with the European Union’s Eco-Design Directive and is shipped in a RoHS compliant package.

Applications

The MAX15059AETE+T is ideal for applications requiring low-noise resistive, high-voltage operation where output voltage accuracy, reliability and efficiency are critical. Examples include: LCD displays and digital instruments requiring low-noise operation, lighting applications such as portable light extracts & replaceable lighting units, relay and control devices requiring high voltage precision and other advanced control applications. The exceptional noise performance of the MAX15059AETE+T make it suitable for automotive, industrial and medical applications, making it ideal for power supply applications that require low noise, high accuracy, and high efficiency.

Working Principle

The MAX15059AETE+T is a fixed frequency current-mode voltage regulator that employs an adjustable pulse-width modulation (PWM) control scheme to regulate the output voltage. In this scheme, the current regulation loop in the module is configured to match the load current to the input voltage. When the load current exceeds the input voltage, the duty cycle of the control pulse is increased in order to reduce the output voltage. Similarly, when the load current falls below the input voltage, the duty cycle of the control pulse is decreased in order to increase the output voltage. The wide range of operating voltage allows the MAX15059AETE+T to be used in both resistive and high power applications.

The MAX15059AETE+T also features low noise operation. This is due to its internal noise rejection circuits and its low-profile ceramic capacitor packaging. These features allow the module to provide low-noise operation even at very high output voltages. It also includes over-temperature protection and soft start circuitry to provide added safety and reliability in bad environment. Furthermore, the MAX15059AETE+T also has an adjustable VOUT reference with an adjustable output voltage.
