库尔沃's ACT4523 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. ACT4523 provides up to 3 A output current at 225 kHz switching frequency.
Active CC is a patent-pending control scheme to achieve highest accuracy sensorless constant current control. Active CC eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit
与传统的恒流开关稳压器相比，该产品消除了相关的功率损耗，实现了更高的效率。保护功能包括逐周期电流限制、热关机和短路时的频率折叠。
ACT4523 SOP -可用8EP package and requires very few external components for operation.
Typical Applications
- 汽车充电器/适配器
- Rechargeable Portable Devices
- General Purpose CC/CV Power Supplies
