Description

Electronic Component Model: SMM766F-974L is an IC chip used for actively controlling the output voltage level of a DC/DC converter. It features an Active DC Output Control (ADOC) function that ensures accurate settings of supply voltages and allows control of supply margining using I2C commands. The device has a high level of accuracy, with a total accuracy of ±0.2% when using an external reference and ±0.5% using the internal reference. It can margin supplies with positive or negative trim pin control within a range of 0.3V to VDD.
