MIC2130-4YTSE-TR Application Field and Working Principle

The MIC2130-4YTSE-TR voltage regulators are a type of DC-DC switching controllers that are widely used in many electronic applications. They offer high efficiency, low power consumption, and accurate voltage control for power sensitive products. This makes them ideal for use in a range of products from wireless base stations to solar inverters.

This specific model from Microchip has a trademarked "simplified constant on-time" architecture, which allows for greater than 90 percent efficiency across a wide input voltage range from 4V to 28V. Its "direct torque control" algorithm is used to provide break before make timing for higher system efficiency. The device also has built in overvoltage protection and thermal shutdown protection for added safety and reliability.

Working Principle

The MIC2130-4YTSE-TR voltage regulators use a Pulse Frequency Modulation (PFM) technique to control the output voltage. PFM is a type of switch mode power supply control that uses an analog input to set the output voltage. The voltage is set by measuring the frequency of the output pulses. The higher the frequency, the higher the output voltage. The PFM provides accurate voltage regulation and fast transient response.

The MIC2130-4YTSE-TR has two main components, the main control IC and the gate drive IC. The main control IC is responsible for setting the output voltage by measuring and setting the PFM frequency. The gate drive IC is responsible for controlling the voltage level of the MOSFETS connected to the switching device. This allows for efficient and accurate control of the output voltage.

The MIC2130-4YTSE-TR has an operating range from 4V to 28V which is suitable for most applications. It also has a wide range of protection features such as overvoltage protection and thermal shutdown protection which make it suitable for use in a wide range of products. The device also has adjustable switching frequency, soft-start and a power-off feature which can be used to reduce noise and power consumption.

Applications

The MIC2130-4YTSE-TR voltage regulators can be used in a wide variety of applications. It is a popular choice for power sensitive products such as wireless base stations, solar inverters and battery chargers, due to its high efficiency, low power consumption and accurate voltage control. It is also suitable for use in high power appliances such as washing machines and refrigerators as it has overvoltage and thermal shutdown protection.
