Step-down DC-DC converter delivers industry-leading performance

Altera's Enpirion EN6362QI power system on a chip (PowerSoC) DC-DC step-down converter is now stocked by Mouser. The EN6362QI PowerSoC is a high-efficiency, integrated synchronous DC-DC step-down buck converter with an integrated inductor, PWM controller, MOSFETs, and compensation. The module is specifically designed to meet the precise voltage and fast transient requirements of high-performance and low-power processors, digital signal processors (DSPs), FPGAs, memory boards, and system-level applications in distributed power architectures. The EN6362QI offers high efficiency of 96 percent, and delivers a continuous 6A at 85C ambient temperature with no de-rating. The EN6362QI PowerSoC also provides excellent line and load regulation over temperature and features a full suite of protections, a precision enable threshold, pre-bias monotonic start-up, and programmable soft-start. In addition, the module provides 1.5 percent VFB accuracy; and its advanced circuit techniques, ultra-high switching frequency, and proprietary integrated inductor technology deliver high-quality, ultra-compact DC-DC conversion that significantly lowers electromagnetic interference (EMI) and enhances productivity. With industry-leading power density and improved performance in the areas of conversion efficiency, output voltage accuracy, load transient response, and output voltage ripple, the EN6362QI PowerSoC is the perfect power system solution for the Altera Cyclone and MAX families of FPGAs or any other power design requiring a tiny, accurate, high-efficiency power source. Measuring just 8 mm × 8mm × 3 mm, the EN6362QI PowerSoC is optimized into a 56-pin QFN module with a total solution size of 170 mm2. Due to its high level of integration and accuracy, the EN6362QI PowerSoC is qualified as a low-risk power supply system solution that contributes to very low failure-in-time rates and dramatically improves system reliability when compared to other discrete power supply solutions. Altera’s Enpirion EN6362QI PowerSoC DC-DC step-down converter is ideal for a variety of noise-sensitive and space-constrained applications that require the highest power density, including point-of-load regulation applications, industrial automation, servers, wireless base stations, test and measurement, and embedded computing devices. For development, the EN6362QI PowerSoC is also supported by the 884-EVB-EN6362QI evaluation board, also available from Mouser stock.
