Claiming to reinvent the dc/dc converter module by turning it inside out, the company’s patent-pending design concept involves using the magnetic material to form the entire package and all components are mounted within the inductor. As a result, the maximum volume is available for the inductor, allowing very low dc resistance and high conversion efficiency. Reportedly, this power supply-in-inductor (PSI2) technology enables a power density up to 1.3 kW/cubic inch. The SPM1004 and SPM1005 Power Modules are the first products to be based on the technology. The SPM1004 Series has a 12-Vdc nominal input with the SPM1005 Series for 5V/3.3V nominal input. Available DC outputs include 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 1V, 0.8V, and 0.6V at up to 6A load current. Operating temperature range is -40°C to +85°C, without forced air or derating. The LGA package measures 9 mm x 11 mm x 2.8 mm for the 5V input and 9 mm x 15 mm x 2.8 mm for the 12V input.
