SSC4S913
Package：SSOP24
The SSC4S913 is a power supply IC, which incorporates a CRM-driven PFC control circuit and an LLC circuit. These internal circuits bring a small-sized, high-efficient, and low-noise power supply system into your application. The LLC stage has the high- and low-side drive circuits. The PFC and LLC stages are highly interlocked in startup and standby operations, thus requiring no individual circuit settings. Supplied in a small SSOP24 package, where multiple protections (e.g., the capacitive mode detection function) are highly integrated, the SSC4S913 offers design friendliness in your high-quality power supply systems with safety. The SSC4S913 has enough functions such as a startup circuit supporting DC input and efficiency improvement at light load.
