TPS53515 Low Power DDR Memory Power Supply Reference Design
Texas Instruments
The PMP20026 reference design provides an efficient low power solution for DDR4 memory. The power supply is powered from a 12V source and regulates the output to 1.2V at up to 6A. The TPS53515 operates in a single phase buck mode at 500kHz that allows for very high efficiency conversion. The solution size is25mm x 15mm. The peak effciency approaches 90% at 5A. At very light loads the efficiency is still above 40%.
