The CXLB74135 is a highly integrated Boost converter and can be widely used in portable applications. The CXLB74135 implements a synchronous high-efficiency step-up boost converter with 10A switch current capability and is capable of providing an output voltage up to 20V. The integrated low Rds(on) MOSFET minimizes physical footprint, maximizes the efficiency, which reduces the power dissipation. Constant current control is utilized to protect the device from overshooting in unwanted conditions. Built-in loop compensation simplifies the circuit and design. PFM is engaged to maintain high efficiency at light load. CXLB74135 guarantees robustness with thermal protection and under voltage lockout
