Overview
NB685A 28 V, 12 A, Low Iq, High Current Synchronous Buck Converter with +/- 1 A LDO and Buffered Reference 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.
Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization.
The DC au...
