26V, 8A, Low IQ, High-Current, Synchronous, Step-Down Converter
The MP8759 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution that achieves 8A of continuous output current and 10A peak output current with excellent load and line regulation over a wide input supply range.
The MP8759 operates with high efficiency over a wide output-current load range based on MPS’ proprietary switching loss reduction technique 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.
Full protection features include over-current limit, over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown.
The converter requires a minimum number of external components and is available in a QFN-12 (2mmx3mm) package.
