LTC4020EUHF | High Power Buck-Boost Multi‑Chemistry Battery Charger

Analog Devices Inc.

Demonstration circuit 2134B is a high power buck-boost multi-chemistry battery charger featuring the LTC4020. The board will accept an input voltage between 15V and 55V. The float voltage of the battery output (BAT) is 25.2V, with 6.3A maximum charge current. The converter output (VOUT) has a voltage range of 21V to 28V, with 8A 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 constantcurrent/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 onboard jumper JP1. The LTC4020 data sheet gives a complete description of the IC operation and application information. The data sheet must be read in conjunction with the quick start guide.
