Application Fields

The MTC15028D12 can be used in a wide variety of applications, including mobile applications, automotive applications, server and storage systems, communications systems and industrial systems. It is able to provide outputs ranging from 0.4V to 28V and up to 10A of output current, making it suitable for a range of power requirements. The device features a high efficiency of up to 94%, low standby power consumption, and a low noise design. It also supports current sharing, enabling it to provide higher levels of power output than traditional single-output converters. The device is capable of operating in a wide range of temperatures, from -40 to +85°C, making it ideal for industrial and outdoor applications.

Working Principle

The MTC15028D12 utilizes a synchronous switching architecture with an integrated high current power MOSFET to provide efficient power conversion and stable output. The synchronous architecture uses two independent pulse-width modulation (PWM) controllers that alternately activate the power switch, allowing for high efficiency and low noise operation. The two controllers are triggered using an internal oscillator which operates at a fixed frequency, providing consistent control of the output voltage. The device achieves high efficiency by using synchronous rectification, which reduces the power loss associated with traditional diode rectification.

The device also features a wide range of protection functions that enable it to operate safely in a range of operating conditions. Over-voltage protection (OVP) and under-voltage protection (UVP) protect the device against excessive or too-low input and output voltages. Over-temperature protection (OTP) and over-current protection (OCP) protect the device against excessive current or temperature, and under-load protection (ULP) helps prevent damage to the device when the load is disconnected.

Conclusion

The MTC15028D12 is a high-performance DC-DC converter designed for efficient operation in a wide range of applications. It utilizes a synchronous architecture with an integrated high current power MOSFET to provide efficient power conversion and stable output. The device also features a wide range of protection functions to ensure safety and reliability in a variety of operating conditions. With its high efficiency, low noise design, and wide operating temperature range, the MTC15028D12 is an ideal solution for a variety of power conversion applications.
