产品概述 返回TOP
The CXPU33104 provide a complete power supply solution. They improve performance, component count, and size compared to other multi-channel controllers in 1-cell Li-Ion. On-chip MOSFETs provide up to 92~95% efficiency for critical power supplies. All channels DC/DC operate at one fixed frequency of 1.5MHz to optimize size, cost, and efficiency. All Synchronous converters operate at pulse skipping mode at light load. They also feature True-Shutdown as well as internal compensation to minimize external component count. The CXPU33104 also provide switched mode Li-ion charger with dynamic power path control. CXPU33104 also has auto NTC-R 100kΩ/10kΩ detection circuit.
