Description
The MP8639 is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter. It offers an ultra-compact solution that can achieve up to 6A of continuous output current (IOUT) and 7.5A of peak IOUT (IOUT_PEAK) across a wide 4.5V to 16V input voltage (VIN) range.
MPS’s proprietary switching loss reduction technique and internal, low on resistance (RDS(ON)) power MOSFETs allow the device to operate at high efficiency across the entire IOUT load range.
Adaptive constant-on-time (COT) control provides fast transient response and eases loop stabilization. The DC auto-tune loop and remote differential sense provide good load and line regulation.
Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown.
The MP8639 requires a minimal number of standard external components, and is available in a QFN-11 (2mmx2mm) package.
