Modular System Creates Power Solutions
Designed to address multiple power-rail applications, the ROA1283003 Power Block from Ericsson can be deployed as power stages controlled by a single or multiple-phase PWM. With an efficiency of 94% at full load, the device accepts input voltages from 7.0 V to 13.2 V, with an output from 0.8 V to 3.3V. Designed for paralleling operation, the PMBus-capable part has a built-in temperature sensor and DCR sense pin. From $10.05 in OEM quantities.
