Working Principle

The DCM3623E50M53C2M70 is a synchronous flyback DC/DC converter working most efficiently with an input voltage between 15 V and 30 V. It can be used with an input voltage between 9 V and 50 V and withstand up to 200 V input transients. The device has an internal soft-start and adjustable frequency of 120 kHz up to 500 kHz. Its start-up time is typically 2.5 ms, and it exhibits very low operating ripple current and minimal EMI in the light load region.

The DCM3623E50M53C2M70 is designed to provide up to 7 A of limited output current and the output voltage is adjustable from 2.5 V to 5.5 V. The converter\'s input voltage operates the quasi-resonant flyback converter in a discontinuous conduction mode, which is required when the output voltage is 0.9 times of the input voltage and the current consumption is more than 4 A. The DCM3623E50M53C2M70 is short-circuit protected and has an Over Voltage Protection limit of 6.8 V.

The DCM3623E50M53C2M70 also includes under-voltage protection, over-temperature protection, and an enable circuit to reduce the output current below 5 mA. The device is thermally enhanced with an exposed pad for additional thermal conduction. This exposed pad should be directly soldered to the PCB for optimal performance.

Conclusion

The DCM3623E50M53C2M70 is a high efficiency and low cost isolated DC/DC converter, and it is designed for use in a variety of industrial and automotive applications. It features wide input voltage range of 9 to 50V, high efficiency of up to 98%, and wide range of protection features. The device is short-circuit protected and has an Over Voltage Protection limit of 6.8 V. It also includes under-voltage protection, over-temperature protection, and an enable circuit to reduce the output current below 5 mA. The DCM3623E50M53C2M70 is a great solution for applications requiring high efficiency and low cost.
