DPD1110 rev. 3 Page 1 of 104 SA4041 Datasheet Description The SA4041 is a digital power processor. One IC offers high-speed analog peripherals, digital accelerators, event control, and digital processing. Its flexibility and performance enables designers to meet demanding compliance standards. Industrial, automotive, and renewable energy applications can benefit significantly from the enhanced performance and reduced component count it offers. The solution addresses many power conversion applications. It easily fits into advanced topologies for AC-DC inverters, battery chargers, and isolated DC-DC converters. The SA4041 has an advanced mixed-signal architecture. The core is a 32-bit RISC 50 MHz micro-processor. A rich set of high-performance digital power peripherals supports the core. Communications, data memory, and general-purpose inputs and outputs (GPIO) are also provided. The SA4041 is a fully software-programmable platform. Programming enables control, monitoring and optimization. Those features allow a design solution to meet aggressive requirements. It also allows for easily differentiated products for competitive markets. Solantro bundles a software development environment with application-specific evaluation hardware to enable customers to achieve faster time-to-market. The SA4041 arose from extensive experience in power systems design. Those systems frequently require optimization of multiple voltages through control loops with adaptive dead-time control of multiple power trains and phases. For example, Totem-Pole PFC, LLC, and Interleaved PFC need such complex control schemes. Here, the core architecture optimizes processor usage by using high speed analog peripherals, digital accelerators and a high performance PLL. The peripherals control high speed loop functions leaving the digital core processor free to maintain low-speed functions. Those functions include slower control loops, protection, optimization and housekeeping. The SA4041 peripheral set is the industrys most complete single-chip offering. It includes configurable high-speed voltage/current sensing, and high-speed comparators (10nS), a variety of high-performance ADCs, DACs, programmable filtering, a multi-event interrupt-based timing engine, a high performance digital PLL, and PWM control for up to 8 power devices are integrated into a single digital power processor. 2019 Solantro The mark Solantro is a registered trademark of Solantro Semiconductor Corp.
