DC2044B

DC2044B demonstration circuit is a 55V buck-boost multichemistry battery charger featuring the LTC®4020. The board will accept an input voltage between 15V and 55V. The float voltage of the battery output (BAT) is 25.2V, with a 3.3A maximum charge current. The converter output (VOUT) has a voltage range of 21V to 28V, with 3A maximum load current. The LTC4020 contains a high-efficiency synchronous buck-boost DC/DC controller and uses a proprietary average current mode architecture. The LTC4020 battery charger can provide a constant current/constant-voltage charge algorithm (CC/CV), a four-step, three-stage lead-acid battery-charge profile or constant-current charging (CC). Battery-chemistry type is selected using on-board jumper JP1.
