Sanken Electric Co., Ltd. PMIC - PMIC - AC DC Converters, Offline Switchers - SSC9522S SSC9522S

The SSC9522S is a controller IC designed for half-bridge resonant type power supplies, featuring a built-in floating drive circuit for high-side power MOSFETs. It operates with a soft-switching mechanism, enhancing efficiency and reducing noise while requiring minimal external components. Key features include a soft start function, capacitive mode operation detection, automatic dead time adjustment, and multiple protection mechanisms such as overcurrent, overload, overvoltage, and thermal shutdown protections. The device supports a wide range of applications, including digital appliances, office automation equipment, industrial equipment, and communication devices. It operates within a voltage range of -0.3 to 35 V for the VCC pin and has a typical oscillation frequency ranging from 28.3 kHz to 300 kHz. The SSC9522S is packaged in an SOP18 format, making it suitable for various PCB designs. Its robust protection features and operational capabilities make it a viable option for engineers seeking reliable power management solutions.
