DC2155A-A

DC2155A-A demonstration circuit is a dual output synchronous step-down converter featuring the LTC®3886, a dual-phase current mode controller. The DC2155A uses discrete MOSFETs in the power stage. The input range of this board is from 18V to 54V. The output voltage can be programmed from 5V to 12V with an output current of up to 12A per phase. For the DC2155A-A version, the factory default setting for the CH0 output is 12V and CH1 output is 5V. In addition, this demo board has an on-board dynamic load circuit, which makes it easy to evaluate the transient performances. The DC2155A powers up to default settings and produces power based on configuration resistors or its program file loaded within its onboard EEPROM without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter aspects of the LTC3886.

• Input supply range from 18V to 54V
• 150KHz factory default switching frequency
