Descrizione

Traduzione AI

The LTC3876 is a complete DDR power solution, compatible with DDR1, DDR2, DDR3 and future DDRX lower voltage standards. The LTC3876 includes VDDQ and VTT DC/DC controllers and a precision linear VTT reference. A differential output sense amplifier and precision internal reference combine to offer an accurate VDDQ supply. The VTT controller tracks the precision VTTR linear reference with less than 20mV total DC error. The precision VTTR reference maintains 1.2% regulation accuracy tracking onehalf VDDQ over temperature for a ±50mA reference load. The LTC3876 allows operation from 4.5V to 38 maximum at the input. The VDDQ output can range from 1.0 to 2.5V, with a corresponding VTT and VTTR output range of 0.5 to 1.25V. Voltage tracking soft-start, PGOOD and fault protection features are provided.
