DESIGN GUIDE

Small, Efficient Power Supply Reference Design for M.2 Form Factor SSD

Description

This small and efficient power supply reference design demonstrates a power solution for M.2 form factor client Solid State Drives. This solution uses 3 DC/DC converters and a 1 Linear Regulator. Furthermore, one of the outputs offers the flexibility to change the output voltage through I2C communication.
