Analog Devices Inc. LTC3883 Demo Board DC1890A contains the circuitry needed to program and verify the EEPROM of the LTC3883 and LTC3883-1 step-down DC/DC controllers. This demonstration circuit includes the LTC3883 installed in a clamshell-style programming socket. The DC1890A demonstration circuit features EEPROM that includes the factory default configuration. LTpowerPlay software (GUI) has to be downloaded and installed to verify the contents of the EEPROM.
