Six-Channel Supply Voltage Marginer And Active DC Output Controller

The SMM605 actively controls the output voltage level of up to six DC/DC converters that use a Trim or VADJ/FB pin to adjust the output. An Active DC Output Control (ADOCTM) feature is used during normal operation to maintain extremely accurate settings of supply voltages and, during system test, to control margining of the supplies using the industry standard I 2 C 2-wire data bus commands. Total accuracy with a 0.1% external reference is 0.2%, and 0.5% using the internal reference. The device CAN margin supplies with either positive or negative trim pin control within a range of 0.35V to VDD. The SMM605 supply CAN range from 2.7V to 5.5V or 6V to 14V to accommodate any intermediate bus supply. The voltage settings (margin high/low and nominal) are programmed into nonvolatile memory. The I 2 C bus is used to enable margin high, margin low, ADOC or normal operation. When margining, the SMM605 will check the voltage output of the converter and make adjustments to the trim pin via a feedback loop to bring the voltage to the margin setting. A margining status Register is set to indicate that the system is ready for test. By SUMMIT Microelectronics, Inc:
