Additional Details

The INN801AGS utilizes primary-side regulation, which eliminates the need for an optocoupler, simplifying the design and reducing component count. It features constant voltage (CV) and constant current (CC) control, providing precise regulation of the output voltage and current. The IC integrates various protection features, including overvoltage protection (OVP) and overcurrent protection (OCP), to ensure reliable operation. The switching frequency is internally set, optimizing for efficiency and EMI performance. It has very low standby power consumption to meet global energy efficiency requirements. The device is available in a compact package, ideal for size-constrained applications. The operating temperature ranges from -40°C to +105°C. It is commonly used in wall adapters and chargers due to its efficiency and small size.
