Power block provides power to multiple rails

Power block provides power to multiple rails

The ROA1283003 is a 30-A power block that addresses the power distribution and management technology called centralized control architecture (CCA). The CCA drives single or multiple switching termination modules. It can be inserted as a power stage controlled by a single- or multiple-phase PWM.

The power block accepts input voltages from 7 to 13.2 V, and provides an output of 0.8 to 3.3 V. It offers a typical efficiency of 94% at full load and 3.3 VOUT . The power block is designed for paralleling operation, allowing scalability. It has a built in temperature sensor device and a DCR sense pin. The device uses a digital interface including I2 C or PMBus, and has a 0.45-in. profile. ($10.05 ea/large qty — available now.)
