Monolithic Power Systems NB675LGL
The NB675L is the lower quiescent current version of NB675. It provides a complete power supply for DDR3, DDR3L and LPDDR2 memory with the highest power density. It integrates a high frequency synchronous rectified step-down switch mode converter (VDDQ) with a 1.0A sink/source LDO (VTT) and buffered low noise reference (VTTREF).NB675LGL Specifications

DESCRIPTION
FEATURES
NB675L is able to deliver 10A continuous output current and 12A peak output current over a wide input supply range with excellent load and line regulation. The Buck converter employs the Constant-On-Time (COT) control scheme, which provides fast transient response and eases loop stabilization. The VTT LDO provides 1.0A sink/source current capability and requires only 10uF ceramic capacitance. The VTTREF tracks VDDQ/2 with an excellent 1% accuracy. Under voltage lockout is internally set as 4.6V. An open drain power good signal indicates VDDQ is within its nominal voltage range.● Wide 4.7V to 24V Operating Input Range
