Introduction

The MAX1675EUA-T is a DC-DC switching regulator containing a voltage regulator, a power MOSFET, and a small-time clock and oscillator. It is designed to provide a simple and low cost solution to the design of low power isolated DC-DC converters. The current-mode control loop and switch embedded in the device are based on a true fractional-N architecture that provides fast transient response. The switch is set up to deliver a constant output voltage of between 0.6V and 5.5V, and draw power from a source voltage of between 0.9V and 8V. The package includes a TTL compatible interface, allowing it to be directly soldered onto a motherboard.

Features

The MAX1675EUA-T is designed for low power DC-DC converters. It provides a high efficiency operation with a wide input voltage range of 0.9V to 8V and an output voltage range of 0.6V to 5.5V. The standard operating frequency is 350kHz, but can be adjusted with the onboard frequency trimming capability. The device also has a shutdown mode that provides a standby current of only 500nA.The device features an adjustable voltage limit and over-temperature protection, low power consumption and an adjustable soft-start. The input/output filter and MOSFET switch make the device suitable for a wide range of input to output voltages and application areas.

Application Field

The MAX1675EUA-T is suitable for applications such as industrial control, home appliances, wireless communication, aeronautic and navigation equipment, and remote sensing. It is also ideal for applications which require a low power, isolated DC-DC converter. It can be used to power small digital logic circuits, current sensors, and RF transmitters. The device is also suited for use in battery-backed systems, providing back-up power for systems that need to maintain power or low power operation even during power outages.

Working Principle

The MAX1675EUA-T works by converting the input voltage to a higher or lower output voltage. The regulation is achieved by operating a MOSFET switch and a small pulse-width modulation (PWM) clock and oscillator. The true fractional-N technology in the device ensures fast transient response. When the device is in steady state, the switch turns on and off in a control loop to regulate the output voltage. The control loop is adjusted by adjusting the MOSFET and oscillator frequency. The PWM and oscillator are combined in a single package with a TTL compatible interface, providing a low cost and efficient solution. The device also features a small operating current, adjustable voltage limit and an adjustable soft-start.

Conclusion

The MAX1675EUA-T is a low power DC-DC switching regulator designed to provide a simple and cost-effective solution to low power isolated DC-DC converters. It has a wide input voltage range of 0.9V to 8V and an output voltage range of 0.6V to 5.5V. The device features a true fractional-N architecture, a TTL compatible interface, low power consumption and adjustable voltage limit. Its compact package and ease of use makes it ideal for a range of applications, from industrial control to battery-backed systems.
