DC-DC converters are electronic devices used to convert electricity from a source of direct current (DC) from one voltage level to another. These converters can be used to increase, reduce, or invert voltage as required, making them vital components in a variety of electrical systems. One example of a DC-DC converter is the TIM 2-0922SM.

Application Field

The TIM 2-0922SM is a surface-mount DC-DC converter designed for use in high-reliability embedded systems. It combines an isolation transformer and an internal DC-DC converter into a single package, allowing for safe and efficient operation in highly regulated environments. The device can be used in a variety of applications, including motor control systems, industrial controls, medical instruments, medical equipment, automotive systems, and telecom systems.

Working Principle

The TIM 2-0922SM is an isolated, step-down type DC-DC converter. This means that it takes an input voltage and reduces it to a desired value in order to provide the necessary power to a connected load. In order to achieve this, the device employs an input voltage of 3 V to 32 V and an output voltage of up to 24 V. The device uses an integrated magnetic core isolation transformer to separate the input and output circuits, eliminating the need for optocouplers and reducing losses associated with ground current.

The device then uses voltage regulating to ensure the output voltage remains stable. This is accomplished by monitoring the output voltage via an isolated feedback loop and adjusting the duty cycle of the internal N-Channel MOSFET switch as needed to compensate for any discrepancies. The device is further protected by built-in over-load and short-circuit protection, which will turn off the power to the load in the event of an over-current situation.

Performance

The TIM 2-0922SM is designed to deliver up to 20 A of output current at an efficiency up to 95%. In addition, the device also offers a wide range of operating temperatures, ranging from -40℃ to +125℃, and is compliant with EN60601-1 medical safety and IEC 61000-4-2, Level 4 EMC standards. The device is further equipped with onboard diagnostics, which can be used to monitor the converter\'s performance and adjust its parameters as needed.

Conclusion

The TIM 2-0922SM is a highly reliable and versatile DC-DC converter designed specifically for use in embedded systems. With its integrated isolation transformer, output voltage regulation, wide operating temperature range, and onboard diagnostics, the device is well suited for applications such as motor control systems, industrial controls, medical instruments, medical equipment, automotive systems, and telecom systems.
