ONSEMI NCP1011ST100T3G Power Supply Controller
The NCP1011ST100T3G is a high-performance monolithic switch-mode power supply controller designed for low standby-power offline SMPS applications. It integrates a 700V MOSFET, fixed-frequency current mode control, soft-start, frequency jittering, short-circuit protection, skip-cycle mode for light loads, and dynamic self-supply without an auxiliary winding. Its silent operation during light loads and built-in protections make it ideal for low-cost, robust power supplies in chargers, adapters, and auxiliary power systems. Available in a SOT-223 package, it ensures efficient, noise-free, and safe operation in compact designs.
