DEMO MANUAL DC1508B

Description

LTC2974/LTC2975/LTC2977/

LTC2978/LTC2978A

Programming Board for PMBus 

Power System Managers

The DC1508B programming board contains the circuitry 

needed to program and verify the EEPROM of the 

LTC2974

LTC2975

LTC2977

LTC2978

, and 

LTC2978A

. This is its 

sole purpose. The DC1508B is shipped with a clamshell 

style programming socket installed. The EEPROM contains 

the factory default configuration. The LTpowerPlay™ *.proj 

file that corresponds to the factory default can be found 

in the GUI.
To properly program and verify the contents of the EEPROM, 

download and install the LTpowerPlay software (GUI).
