General Description

The NB685A provides a complete power supply with the highest power density for DDR3, DDR3L, LPDDR3, and DDR4 memory.

It integrates a high-frequency, synchronous, rectified, step-down, switch-mode converter (VDDQ) with a 1 A sink/source LDO (VTT) and buffered low noise reference (VTTREF).

The NB685A 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.

Overview

NB685A 28 V, 12 A, Low Iq, High Current Synchronous Buck Converter with +/- 1 A LDO and Buffered.

Key Features

  • include OC limit, OVP, UVP, over-temperature warning (OTW), and thermal shutdown. The converter requires a minimum number of external components and is available in a QFN 3mm x 3mm package.
