This article will discuss the application field of the MIC222YML-TR switching regulator and the working principle.

Application Field

The MIC2207YML-TR is a fixed frequency, non-synchronous, and high-efficiency general-purpose DC/DC buck switching regulator. This regulator is designed to operate from an input voltage range of 5V to 36V and is capable of providing a regulated output voltage from 0.6V to 5V (adjustable with external resistor divider). It also provides an internal protection circuit for thermal shutdown and for over-current protection. It can be used for voltage step-down applications in a wide range of applications such as 5V to 12V power supply, 5V to 3V power supply, 5V to 15V, 9V to 5V, 16V to 3V and more.

The MIC2207YML-TR has a 2.0MHz switching frequency and is capable of providing high-efficiency performance up to 96%. The high-efficiency, output accuracy, and small size of the MIC2207YML-TR make it ideal for a wide range of applications. Its small footprint and temperature range makes it suitable for portable and automotive applications.

This device is suitable for applications such as cellular phones, PDAs, computers, telecommunications equipment, industrial automation and automotive applications. It is also suitable for mains powered applications, as it is RoHS compliant and has low power consumption.

Working Principle

The MIC2207YML-TR DC/DC switching regulator works on the principle of pulse width modulation (PWM), which means the output voltage is regulated and kept relatively constant. The output voltage is determined by switching between the input and output capacitors to create a series of pulses which are then “chopped” on and off. The average voltage of these pulses is proportional to the input voltage and the duty cycle of the switching pulses.

To achieve maximum efficiency, the regulator uses a synchronous rectifier to return energy to the input when the load is enabled. This reduces power dissipation and allows the regulator to achieve a high efficiency of up to 96%. The high efficiency also increases the operating temperature range of the device.

The MIC2207YML-TR also includes a Soft-Start feature to slowly increase the output voltage of the regulator as it starts up. This prevents output voltage undershoot and protects the system components from inrush current. The MIC2207YML-TR also features an enable/disable input to control the output of the regulator.

Conclusion

The MIC2207YML-TR is a fixed frequency, non-synchronous switching regulator designed for better performance and higher power efficiency than linear regulators. This DC/DC switching regulator operates on a pulse width modulation circuit which provides a regulated output voltage with a maximum output current of 3A and an input voltage range from 5V to 36V. It is suitable for a wide range of applications in the telecom, industrial, and automotive sectors. The MIC2207YML-TR also has low power consumption and a wide temperature range which makes it suitable for mains powered and portable applications.
