Product Description
MP9943GQ-Z Integrated Circuit Chip
High Efficiency 3A 36V Synchronous Step Down Converter With Power Good
The MP9943GQ-Z is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. This compact solution delivers 3A peak output current with excellent load and line regulation across a wide input supply range. Synchronous mode operation ensures higher efficiency throughout the output current load range.
