DC1162A-B: Demo Board for LTC4223 Dual Supply Hot Swap Controller for Advanced Mezzanine Card

Demonstration circuit 1311 is a Telecom isolated DC/DC converter featuring the LTC3805/-5 constant frequency current mode flyback controller. The DC1311 converts 18V to 72V input voltage to an isolated 3A of output current at 3.3V. The 300kHz constant frequency operation is maintained down to very light load to reduce low frequency noise generated over a wide range of load current. The converter provides high output voltage accuracy (typically ±2%) over wide load range with no minimum load requirement. The DC1311 also provides non-isolated design by removing opto coupler and LTC4430 circuit. The demonstration circuit can be easily modified to generate different output voltages up to 15V. As output voltage is increased, the maximum output current must be reduced to limit the output power to no more than 10W.

Demonstration circuit 1590B is a dual output synchronous buck converter featuring the LTC3880EUJ, 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.
