Description
Demonstration circuit 2134A is a high power 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 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 (JP1: CC/CV,with mode pin grounded), constant-current charging (JP1:CC, with mode pin floated), or charging with an optimized4-step, 3-stage lead-acid battery charge profile (JP1: leadacid, with mode pin connected to INTVCC).
The LTC4020 data sheet gives a complete description of the IC operation and application information. The data sheet must be read in conjunction with this quick start guide.
