Introduction High Efficiency, 4.5V to 14V Input, Dual Output
The LTC 3876 is a complete DDR power solution, DDR Power Supply
compatible with DDR1, DDR2, DDR3 and DDR4 lower Figure 1 shows a DDR3 power supply that operates
voltage standards. The IC includes VDDQ and V TT DC/ from a 4.5V to 14V input. Figure 2 shows efficiency
DC controllers and a precision linear V TT reference. curves for discontinuous and forced continuous
