Monolithic Power Systems NB685 | Demoboard EVNB685-Q-01A

Beschreibung

The NB685 provides a complete power supply for DDR3, DDR3L, LPDDR3, and DDR4 memory with the highest power density. It integrates a high frequency synchronous rectified step-down 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 rang based on MPS proprietary switching loss reduction tech and internal low Ron power MOSFETs.
