The SC81442 is a synchronous Buck converter with a wide input voltage range from 3V to 36V, providing 4A current capability options. The converter regulates the output voltage at customized voltage through setting the divider resistors. It also provides highly efficient output current and fast loop response with current mode control. The SC81442 is specifically designed for universal applications. The device integrates user-optional spread spectrum. The switching frequency can also be synchronized to external clock through multiplexing EN/SYNC pin. For fixed frequency parts, a power good function is available by the PG pin. For better thermal performance, SOP-8 package with a thermal pad is available. In addition, the device incorporates highly efficient PFM mode. The SC81442 employs both peak current limit and valley current limit to help protect the device from overload as well as provides short-period heavy current capability. It also provides thermal shutdown, input UVLO, output short-circuit protection to enable systematical robust operation.
