Product Description

The EV8719-Q-00A is the evaluation board for MP8719. The MP8719 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).

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 22uF ceramic capacitance. The VTTREF tracks VDDQ/2 with an excellent 1% accuracy.

Full protection features include OC Limit, OVP, UVP and thermal shut down and Over temperature warning (OTW).

The converter requires minimum number of external components and is available in QFN 3x3 packages.

MP8719


26V, 12A, Low IQ, High-Current, Synchronous Buck Converter with ±A LDO and Buffered Reference

The MP8719 provides a complete power supply with the highest power density for DDR3, DDR3L, LPDDR3, and DDR4 memory. The MP8719 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 MP8719 operates at high efficiency over a wide output current load range based on MPS’s proprietary switching loss reduction technology and internal low RDS(ON) 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 of sink/source current capability and requires only a 22μF ceramic capacitor. The VTTREF tracks VDDQ/2 with excellent 1% accuracy.
Full protection features include over-current (OC) limit, over-voltage protection (OVP), under-voltage protection (UVP), over-temperature warning (OTW), and thermal shutdown.
The MP8719 requires a minimal number of external components and is available in a QFN-16 (3mmx3mm) package.
