PSI² Power Supply in Inductor Efficiency The high performance inductor minimizes losses at full load, and the circuit topology maintains excellent efficiency over the entire load range. The next step in integration! SPM1004 SUMIDA offers a new range of fully integrated power modules which feature outstanding performance with industry-leading power density. SUMIDA has leveraged its extensive experience in inductor technology to achieve the highest available efficiency as well as optimized packaging for thermal management. In this product all components are integrated within the inductor which provides significant benefits: •The maximum amount of magnetic material is used, rather than plastic fillers, allowing low loss and high efficiency •The coil can use thicker wire for lower resistive losses and higher efficiency •The magnetic material is thermally conductive, avoiding hot spots •The inductor provides electromagnetic shielding for the switching components •The integrated power module is fully tested and dramatically simplifies the end product design •The small size and very low profile (3 mm) package reduces board space, allowing higher density designs SPM1005 Thermal The high conductivity of the magnetic material maintains a uniform temperature across the module and ensures that there are no "hot spots" (Figure 1). The measured surface temperature is reduced by 11.5°C compared to a power module with an internal inductor under identical conditions (Figure 2). Figure 1 - SPM1005 Figure 2 - Comparison Transient response The circuit topology has been chosen to provide an excellent response under transient load. The figure below shows less than 20mV transient under a 3A load step (SPM1004, Vin=12V and Vout=1V): SPM1004 (Vin=12V and Vout=1V) • • SUMIDA Components & Modules GmbH | Dr. Hans-Vogt-Platz 1 | 94130 Obernzell Phone: 08591/937-100 | [email protected] | www.sumida-eu.lcom Updated February 4, 2016 PSI² Power Supply in Inductor EMI performance Package size The module is supplied in a Land Grid Array (LGA) package with a very low profile (3mm), and the footprint is only 9x15mm (SPM1004 and SPM1006) or 9x11mm (SPM1005). Very few external components are required because all major components are internal to the module, and because of the high efficiency no forced airflow is needed up to 85°C ambient. This makes it ideal for high density applications. All internal power traces are very short, minimizing the loop area and reducing radiated EMI. The inductor material is conductive and acts as a shield over the internal components, further reducing EMI. Evaluation boards Design time The module is fully tested during production and is guaranteed to meet specifications. This simplifies the end product design and PCB layout, and avoids surprises during system testing. In contrast, a power design based on separate components on the end product PCB is higher risk and typically takes longer to develop and debug.
