Product Recommendation Maker Dynamics Applications

Product Recommendation Maker Dynamics Applications

Do we need to lay copper foil underneath the inductor for DC-DC power supply? Inductors have alternating current, and laying copper at the bottom of the inductor will generate eddy currents on the ground plane. The eddy current effect will affect the inductance of the power inductor, and eddy currents will also increase system losses. At the same time, the noise generated by alternating current will increase the noise on the ground plane, which will affect the stability of other signals. From the perspective of EMC, laying copper on the bottom of the inductor and a complete ground surface is beneficial for EMI design; The current production process of inductors has been upgraded, and shielded inductors are used. There are very few leaked magnetic induction lines, which have little impact on the inductance of the inductors and are also beneficial for heat dissipation.

SUNLORD integrated power inductor helps Qualcomm 8750 AI flagship mobile phone platform land The upgrade of performance cannot be separated from the upgrade of hardware, and the power supply is a very important part of it. To improve AI performance, the Qualcomm 8750 platform has adjusted the nuclear power supply inductance to a value of 0.24uH for the first time, and proposed Isat to meet the high requirements of 6.5A&DCR<24mohm. Shunluo Electronics was the first to develop the material MWTC1412065SR24MTB02 suitable for the Qualcomm 8750 platform, and obtained Qualcomm testing certification, making it the first domestically produced product.
