This type of regulator offers impressive electrical properties, making it suitable for many applications. The main characteristics of this product include its current step-up/step-down capability, adjustable voltage range and ultra-low quiescent current consumption.
Let us see the applications of MAX20076ATCB/V+T and its working principle.
Application Field of MAX20076ATCB/V+T
The MAX20076ATCB/V+T was designed for off-board use and intended to supply power to a load from a single, wide voltage range supply. This impressive DC-DC converter has a versatile input voltage range from 2.6V to 26V, and an adjustable output voltage from 0.9V to 17V. It is a perfect choice to power many applications such as industrial and telecom power supplies, distributed power systems, DC/DC converters and switch mode power supplies.
Maxim Integrated’s device includes a wide range of protection features such as over-temperature protection (OTP) with adjustable timeout and selectable hysteretic or latch behaviour, open-circuit protection, galvanic isolation and many more. Therefore, the MAX20076ATCB/V+T is a reliable source of clean and efficient power.
Working Principle of MAX20076ATCB/V+T
The MAX20076ATCB/V+T is a step-up or step-down DC-DC converter based on the hysteretic control topology. This topology is based on a switch that is turned on and off at a specific point of the cycle in order to keep the output voltage constant. In addition, this device is integrated with two outputs - one for step-up/down operation and another one for voltage regulation.
The first output, the step-up/down output, is based on the principle of pulse-width modulation (PWM). PWM is used to generate a square-wave at a given frequency from a triangle waveform generated by an internal oscillator. The average voltage of the square wave is proportional to the duty cycle, meaning that the output voltage can be adjusted by varying the duty cycle of the PWM signal.
The MAX20076ATCB/V+T synchronous rectifier topology is also used in order to reduce the ripple current that it produces. This device includes an on-chip active diode and a PMOS switch, which ensures that the output voltage remains constant regardless of the load current. With this topology, the device is able to regulate and monitor the output voltage even in harsh environment.
In conclusion, the main features of the MAX20076ATCB/V+T device include its wide input voltage range, adjustable output voltage, improved power conversion efficiency and flexible protection features. This device is ideal for applications that require a reliable source of power and is offered in different package options.
