Dual step-down µModule regulator provides two 25 A outputs or a single 50 A output with digital power system management. The regulator operates from a 4.5 V to 16 V input supply and supports output voltages down to 0.5 V. PMBus and I2C-compatible control provide configuration, sequencing, margining, telemetry, and fault management. The module integrates switching controllers, power FETs, inductors, and support components in a compact BGA package.
