A General-Regression-Neural-Network Based 5V-to-48V Three-Level Buck/Boost Power Converter with 40dB PSRR 90%-Efficiency for SSD Power Loss Protection

Solid-state drives (SSDs) are widely used in data centers, workstations and PCs to replace hard drives for their high data rate, low energy consumption and compact size. To protect the SSD’s cache buffers and mapping table during unpredicted power loss, power loss protection (PLP) circuits are required as a backup power supply to power the SSD for 10s of milliseconds. As shown in Fig. 1, when the ...
