Product Details

The DC1540B is a demonstration system for the LTC2977 8-channel I²C/SMBus/PMBus Power System Manager with EEPROM. It consists of 2 circuit boards namely the DC1360B and DC1361B. The DC1360B contains all the circuitry needed to insert the LTC2977 into a power system and control eight power supplies. The DC1361B contains eight power supplies (LTM4603EV) which are configured to be controlled by an LTC2977. Together these two boards form a sophisticated, 8-channel, digitally programmable power supply.

Product Details

Demonstration circuit DC1083A-A features the LTM4603, the high efficiency, high density step-down μModule^® regulator. The input voltage range is from 4.5V to 20V. The output voltage is jumper programmable from 0.6V to 5V. The rated load current is 6A, but derating is necessary for certain V_IN, V_OUT, and thermal conditions. The LTM4603 can be synchronized to an external clock signal by applying the clock to the PLLIN pin.
