CXLB74205 is a multifunctional power management SOC with integrated boost converter, lithium battery charge management, and battery power indication, providing a complete power solution for mobile power.
The high integration and rich functions of the CXLB74205 make it require only a few peripheral devices in application, and effectively reduce the size of the overall solution and reduce the BOM cost.
CXLB74205 only one inductor to achieve buck and boost function. The DC-DC converter operates at 350KHz and can support low-cost inductors and capacitors.
The CXLB74205 synchronous boost system provides a maximum output current of 1.0A with a high conversion efficiency of 91%. When there is no load, it will automatically enter the sleep state, and the quiescent current will drop to 50uA.
The CXLB74205 uses switching charging technology to provide a maximum current of 0.3A and a high charging efficiency of 93%. The built-in IC temperature and input voltage intelligently adjust the charging current.
CXLB74205 support 1, 2, 3, 4 LED power display.
