General description

The NB685 provides a complete power supply with the highest density for DDR3, DDR3L, LPDDR3, and DDR4 memory. It integrates a high-frequency, synchronous, rectified, stepdown, switch-mode converter (VDDQ) with a 1A sink/source LDO (VTT) and buffered low noise reference (VTTREF).

The NB685 operates at high efficiency over a wide output current load range based on MPS proprietary switching loss reduction technology and internal low Ron power MOSFETs. Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop provides good load and line regulation.

The VTT LDO provides 1A sink/source current capability and requires only 22ÎĽF ceramic capacitors. The VTTREF tracks VDDQ/2 with excellent 1% accuracy.

Full protection features include OC limit, OVP, UVP, thermal shutdown, and over-temperature warning (OTW).
