Working principle of NDTD4815C

The NDTD4815C is a synchronous step-down DC/DC converter with a unique design that combines the functions of a buck converter and a synchronous rectifier. The NDTD4815C achieves high efficiency and low component count by synchronously rectifying the input voltage and placing all active elements in the output branch. This unique topology enables the NDTD4815C to operate in CCM or DCM mode for improved light load efficiency and improved low EMI.

The NDTD4815C operates with a fixed frequency of 150 kHz. The fixed frequency operation of the NDTD4815C permits the use of higher input and output capacitors, for improved ripple, noise and transient response conditions. The NDTD4815C also employs constant on-time control, providing precise output voltage control, with little overshoot, and fast transient response for load and line changes.

The NDTD4815C features low quiescent current, and also offers optional applications with 6 A and 10 A operational sets. Investing in the NDTD4815C will result in high efficiency and power losses. Most importantly, the NDTD4815C features soft-start function for power-on, as well as output short-circuit protection, leading to safe operation in any case.

Conclusion

In conclusion, the NDTD4815C is an ideal choice for a wide range of applications, utilising the latest technologies, build with the highest quality standards. The features of the NDTD4815C bring convenience and reliability for any kind of power supply requirements, no matter what the scale.
