Introduction of the synchronous rectification NVDC battery boost/buck charging controller 'bq25703A'.
With a synchronous rectification NVDC battery buck-boost charging controller, it is possible to build a solution with fewer components and high efficiency for charging applications that accommodate various types of batteries while being space-constrained. The NVDC-1 configuration allows the system to be regulated to the battery voltage while maintaining the system above its minimum voltage. The system can continue to operate even if the battery is fully discharged or removed. When the load power exceeds the rated input power, the battery transitions to a supplemental mode to prevent overload of the input power source. Additionally, it charges the battery from a wide range of input power sources, including USB adapters, high-voltage USB PD sources, and traditional adapters. *For more details, please contact us.
Low price, high cost performance.
PWM charging circuit adopted. Achieves high-efficiency charging with a solid-state structure. Low price, high cost performance. Automatic temperature compensation (-28mV/℃). Filled with epoxy resin. The wires have a Hypalon coating for high weather resistance.
High voltage module connection available, equipped with MPPT function.
**Features** - High voltage modules for residential industry and others can be connected. It can connect to high output voltage residential industry and thin-film solar cell modules. With the MPPT function, it can charge the battery without wasting the power generated by the solar cells. In standalone solar power systems, it can control up to 3.2 kW. - MPPT Control. The optimal operating point for maximum output of the solar cell array constantly fluctuates due to changes in solar radiation and module temperature. MPPT control follows the optimal operating point of the solar cells that changes according to the situation, ensuring that maximum power from the solar cells is always obtained. - Power loss reduction with maximum efficiency of 99%. Conventional controllers wasted energy due to the large difference between battery voltage and the array's maximum operating voltage. With MPPT technology, it operates at the maximum operating voltage at all times, resulting in almost no power loss. - High durability. The housing is protected from dust and humidity due to epoxy filling and insulation coating. Equipped with protection circuits for overload protection, circuit short-circuit, high voltage protection, over-temperature protection, and nighttime current backflow prevention, it extends the lifespan of the entire system. *For more details, please refer to the catalog download.*
