MIC21000: High Performance Digital PWM Controller
The MIC21000 is a configurable true-digital PWM controller for high current, non-isolated DC/DC power supplies in computing and telecom applications. The MIC21000 is designed to drive industry-standard DrMOS devices; therefore current capability can be easily scaled. The MIC21000 integrates a digital control loop, optimized for maximum flexibility and stability, as well as load step and steady-state performance. In addition, a rich set of protection and monitoring functions are provided. The on-chip, non-volatile memory (NVM) and an I2C/PMBus™ interface facilitate communication and configuration.
