SMM605(2011) Datasheet - Summit Microelectronics

INTRODUCTION
   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 I2C 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.
