Product Description

The TPS51100DGQ is a 3A Source/Sink DDR Terminator Regulator specifically designed for low-external component count systems where space is a premium. The TPS51100 maintains fast transient response, only requiring 20µF (2 x 10µF) of ceramic output capacitance. It supports remote sensing functions and all features required to power the DDR and DDR2 VTT bus termination according to the JEDEC specification. The part also supports DDR3 VTT termination with VDDQ at 1.5V (typical). In addition, the TPS51100 includes integrated sleep-state controls, placing VTT in Hi-Z in S3 (suspend to RAM) and soft-off for VTT and VTTREF in S5 (suspend to disk). The soft-start function of the VTT is achieved via a current clamp, allowing the output capacitors to be charged with low and constant current that gives linear ramp-up of the output voltage. The current-limit threshold is changed in two stages using an internal PowerGood signal.
