MAX668EUB is an integrated circuit (IC) component designed by Maxim Integrated. It is a step-up switching regulator that operates with input voltages as low as 1.8V and delivers output voltages up to 28V. This versatile IC offers various key features that make it ideal for power management applications.
One of the notable features of the MAX668EUB is its high efficiency, achieved through a fixed-frequency pulse-width modulation (PWM) control scheme. It utilizes a synchronous rectifier to minimize power loss during operation, making it an efficient choice for battery-powered devices and other energy-sensitive applications.
To ensure precision regulation, this IC incorporates a voltage feedback loop that adjusts the duty cycle of the switching regulator. The MAX668EUB also offers an adjustable current limit function, allowing users to control the maximum current that can be drawn from the output. Such flexibility makes it suitable for a diverse range of load conditions and system requirements.
Furthermore, the MAX668EUB includes a built-in oscillator with a frequency range of 100kHz to 600kHz, enabling designers to optimize the switching frequency based on their specific needs. This flexibility enables efficient regulation while minimizing electromagnetic interference (EMI).
The IC also provides comprehensive protection features, such as thermal shutdown and overvoltage protection, safeguarding the system against potential faults. Additionally, it has an enable input pin that enables the device to quickly enter and exit a low-power shutdown mode, reducing power consumption during idle or standby periods
