MAX765ESA

MAX765ESA Introduction

The MAX765ESA is a step-down DC-DC voltage regulator integrated circuit manufactured by Maxim Integrated. It is a pulse-width modulation (PWM) current-mode (CM) DC-DC buck regulator that offers low noise output and excellent transient response with only 4 ms settling time across a wide input voltage range. The MAX765ESA is an ideal solution for powering low voltage electronics such as communication applications, medical equipment, and industrial control systems.

Application of MAX765ESA

The MAX765ESA is designed to be used as a voltage regulator in a variety of applications. Its primary function is to step-down input voltages, delivering a constant output voltage to low voltage electronic devices. This CM PWM DC-DC buck regulator can handle input voltages of up to 100 V, and can deliver output voltages of up to 40 V. It is capable of a duty cycle of up to 90%, making it suitable for a wide range of applications.

The MAX765ESA is particularly well-suited for applications where high current and low noise are required, such as cameras, modems, wireless base stations, and routers. Its high power handling capability and low output noise make it an ideal solution for applications such as radiography equipment, biomedical instrumentation, and industrial equipment.

Working Principle of MAX765ESA

The MAX765ESA is a pulse-width modulation (PWM) current-mode (CM) DC-DC buck regulator. It operates on the principle of "pulse-width modulation", i.e. the output voltage is regulated by modulating the width of the output pulses. This is done by using a feedback loop to monitor the output voltage, and then adjusting the duty cycle of the output pulses accordingly. The MAX765ESA is designed to operate over a wide input voltage range of up to 100 V, allowing it to deliver a constant output voltage, even when the input voltage fluctuates.

The MAX765ESA also features a high output current capability of up to 2 A, allowing it to be used in applications where high current is required. It has a low output noise rating of just 1 mV for ripple and noise, making it suitable for noise-sensitive applications. On top of this, the MAX765ESA has excellent transient response, featuring an output voltage settling time of just 4 ms over its entire operating range.

Conclusion

The MAX765ESA is a CM PWM DC-DC buck voltage regulator manufactured by Maxim Integrated. It is designed to handle input voltages of up to 100 V, and can deliver output voltages of up to 40 V. It provides excellent performance when it comes to load regulation, transient response, and output noise. Its high power handling capacity, low noise output, and excellent transient response make it an ideal choice for a variety of applications, such as cameras, modems, wireless base stations, and biomedical and industrial equipment.
