Introduction to MIC5190YMM-TR

The MIC5190YMM-TR is an advanced linear regulator controller designed for precision, low-dropout regulation of output voltages ranging from 0.4 V up to 8 V. It offers the ultimate performance of the MIC5190 family of linear regulator controllers in a low-profile, space-saving (YMM-TR) package. It includes features to optimize system performance, including low supply current (1.5 mA typ), low dropout voltage (150 mV typ at 500 mA), adjustable current limit, and a logic pin to enable and disable the device. This device is ideal for a wide range of applications that require high power conversion efficiency, such as portable electronic applications, notebook and other battery-powered equipment, as well as industrial, automotive and communication systems.

Application field

The MIC5190YMM-TR is commonly found in a wide range of applications such as notebook and other battery-powered equipment, portable electronic devices, and other high-power conversion devices requiring a high degree of accuracy and precision when regulating an output voltage. The device is also suitable for automotive, industrial and communication systems needing low dropout voltage and low supply current such as motor controllers, analog modems and digital cameras. Due to its good power conversion efficiency, it can be used to lower the amount of heat dissipated, allowing the device to operate cooler in thermal-sensitive environments.

Working principle

The MIC5190YMM-TR is designed to sense, regulate, and control the output voltage of a power supply, with a specified degree of accuracy and autonomously from a remote control source. It works by sending a control signal to a remote load, which then synchronously adjusts the duty cycle of its OCx output pin, in accordance with the load\'s requirements. This results in the load being able to remain constant over a wide range of operating conditions. In addition, the MIC5190YMM-TR also employs a low-dropout (LDO) design, wherein the output voltage is maintained at a constant level independent of changes in load or source voltage. This will keep the output voltage stable even when the input voltage is close to the output voltage. The MIC5190YMM-TR also includes features such as adjustable current limit, enabling the device to be programmed to protect the system against high current consumption. In addition, it has a logic pin to enable/disable the device, providing a simple and cost-effective way of controlling the output current. Lastly, the low-profile YMM-TR package allows the device to be mounted in small spaces, making it suitable for use in portable and embedded applications.

Conclusion

The MIC5190YMM-TR is an advanced linear regulator controller designed for precision low-dropout voltage regulation of output voltages ranging from 0.4 V up to 8 V. It offers high power conversion efficiency and variability, enabling its use in a diverse range of applications from notebook and other battery-powered equipment to automotive, industrial and communication systems. With features like adjustable current limit, logic pin to enable/disable, and a small package size, the MIC5190YMM-TR can provide robust and reliable power supply control and regulation for a variety of applications.
