Working principle

The SUCS102415C-C combines state of the art AC/DC power conversion and DC/DC conversion techniques. It relies on synchronous rectification to convert the input DC voltage to an intermediate DC voltage. The intermediate DC voltage is then converted to the output voltage through an LLC resonant converter. The LLC resonant converter is made up of an inductor, two capacitors, two switches, and two diodes. During operation, the output voltage is generated by the resonant oscillation between the capacitors and inductor. The two switching MOSFETs alternately turn on and off, allowing the inductor\'s energy to be transmitted to the output capacitors and generate the output voltage.

In order to maintain high efficiency, the LLC resonant converter must operate at a specific frequency. The frequency is determined by the size of the inductor and capacitors as well as the output voltage. The SUCS102415C-C uses an integrated digital pulse width modulation (DPWM) controller to adjust the switching frequency according to the output voltage, helping to maintain high efficiency over the full load range. In addition, the SUCS102415C-C has built-in protection mechanisms such as over-voltage protection, over-temperature protection, over-current protection, and short-circuit protection.

Conclusion

The SUCS102415C-C DC/DC converter is suitable for a wide range of applications and offers high efficiency, wide input voltage range, and high output power. It uses an integrated synchronous rectification and LLC resonant converter to convert the input voltage to the desired output voltage.
