PMBus-programmable single-phase buck controller
It belongs to the PolyPhase® family and integrates an I²C / PMBus serial interface for real-time telemetry and configuration — output voltage, current limits, sequencing, and fault thresholds are set over the bus, trimming the need for external resistor dividers and trimming pots on the production line. The controller drives external N-channel MOSFETs and supports clock synchronization for multi-rail phase-spreading to reduce input ripple.
The PMBus interface (clocked over I²C) lets a system controller read output voltage, current, and temperature, and dynamically adjust the output during operation.
