Richtek offers diverse DDR memory power solutions including linear DDR terminators and PMICs. The linear DDR terminators have both source and sink functionality and provide very tight output voltage regulation. These parts can be used with various types of (LP)DDR memory. The low Vin linear DDR terminators require an external low power bias voltage. Selecting a suitable product for your applications should be based on the DDR type, current rating and features such as output voltage sensing, REFOUT and different power state settings via S3/S5 pins.
Power solutions for various types of DDR memory from DDR1 to DDR4 as well as Low Power (LP) DDR3/4.
