摘要：该电路包括电池充电器（ MAX712 ）处理充电器的电源部分和降压开关稳压器（ MAX5089 ） 。通过控制稳压器为电池充电控制器MAX712的行为，生产为7V至16V的输出。从任何能够提供所需的快速充电电流，这种情况必须等于输出电压的总和（二加系列充电电池的数量）乘以1.7V的直流电源。Maxim > App Notes > Battery Management Power-Supply Circuits Keywords: switchmode battery chargers, NiMH/NiCd battery chargers, stepdown regulators, constant-current supplies, dV/dt termination Aug 09, 2010 APPLICATION NOTE 4496 NiMH/NiCd Switchmode Battery Charger Has dV/dt Charge Termination Abstract:This circuit includes a battery charger (MAX712) and step-down switching regulator (MAX5089) for handling the power portion of the charger. By controlling the regulator the MAX712 acts as a battery-charge controller, producing outputs of 7V to 16V. It operates from any DC source capable of delivering the desired fast-charge current, with this condition: the output voltage must equal 1.7V multiplied by the sum of (two plus the number of batteries to be charged in series). A similar v……
