Micrel has introduced a true-digital PWM controller for high-current, non-isolated DC-DC power supplies in cloud computing and telecoms applications.

Created to operate with an external market typical DrMOS at the same time as Micrel’s proprietary IntelliMOS answer, the MIC21000 might be utilised for +12V or +5V step-down point-of-load energy supplies.

Based on Brian Hedayati, vice president of marketing at Micrel, the escalating demand for fault tolerant continuous operation for cloud servers calls for power management systems capable of monitoring all the operating energy situations and responding to failures in actual time.

“Digitally controlled power management products allow program designers to optimize their styles by means of software program changes lowering design cycle time,” mentioned Hedayati.

The device tends to make use of non-linear handle to improve transient response.

A I2C/PMBUS interface makes it possible for for true time monitoring of input voltage, output voltage/current and internal/external temperature.

The MIC21000 can operate from a single bias supply voltage of 5V or 3.3V. The device is out there inside a 24-pin 4mm x 4mm QFN package with an operating temperature variety from -40 oC to +85 oC.
