MPQ8645PGVT-0000-Z M8645P PMBus Synchronous Buck Converter
The MPQ8645PGVT-0000-Z M8645P is a highly integrated, PMBus-compatible, high-frequency synchronous buck converter designed to deliver exceptional performance in a compact form factor. With a silk-screen marking of M8645P, this converter offers a comprehensive power solution with up to 30A continuous output current per phase.
Featuring a low RDS(on) integrated power MOSFET, the MPQ8645P ensures efficient power delivery with minimal losses. Lossless and accurate on-chip current sensing enables precise current control and management. With a reference voltage accuracy of 0.5% over a wide junction temperature range of 0°C to 70°C, the MPQ8645P guarantees consistent and reliable output voltage regulation. Supports true remote sensing of output voltage for accurate voltage control and monitoring.
Typical Applications
- Hashboard / ASIC core power — high-current synchronous buck for hashboard domain power.
- Telecommunications equipment — base station and infrastructure power.
- Network equipment — switch / router / datacenter power conversion.
- Server systems — datacenter point-of-load conversion.
- Production refurbishment — bulk buck converter stock for line-based rebuilds.

FAQ — MPQ8645PGVT-0000-Z Synchronous Buck
Q: MPQ8645P vs MP8796B — which to choose?
A: Both are PMBus-compatible MPS buck converters with 30A per-phase output. Differences: pinout, configuration storage approach, target market. For OEM-spec repair, match the part number on your board. For new designs, pick based on availability and feature match.
Q: Why PMBus matters?
A: PMBus is the digital power-management standard for servers / telecom / mining. Allows the host MCU to read telemetry (voltage / current / temperature), program output voltage, configure protections. Modern hashboard control boards rely on PMBus for hashboard health monitoring.
Q: True remote sensing — what does that mean?
A: Remote sensing measures voltage at the load instead of at the converter output. Compensates for IR drop in PCB traces — important on high-current rails where trace resistance causes meaningful voltage error. Standard for precision rails.
Q: Bulk pricing for OEM / repair?
