DC1590B-A - LTC3880EUJ Demo Board (RSENSE) I Vin Range: 6.5V to 24V, VOUT0 = 0.5V to 4V @ 20A, VOUT1 = 0.5V to 5V @ 20A, PMBus Controlled, works w/ DC1613A
Demonstration circuit 1590B is a dual output synchronous buck converter featuring the LTC®3880EUJ, a dual output peak current mode controller with digital power system management. There are two versions of the board available: DC1590B-A senses the output current across a sense resistor and has a default switching frequency of 350kHz, and DC1590B-B senses output current with the inductor DCR and has a default switching frequency of 425kHz. Either version can be populated with the LTC3880EUJ-1 (which allows the user to provide bias power to the IC from an external power supply) instead of the LTC3880EUJ. These boards provide two programmable outputs of 20A each. The factory default settings are 1.8V for each output.
