MP8719 26V, 12A, Low IQ, High-Current, Synchronous Buck Converter with ?A LDO and Buffered Reference

Product Detail

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? 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 22? 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.
