Additional Details

Due to the lack of publicly available datasheets, it's difficult to provide exact specifications. However, based on typical PMIC characteristics, one can expect the BL9198-33BAPURN to operate with an input voltage range of approximately 2.7V to 5.5V. Output voltages may include 3.3V, 1.8V, and 1.2V, depending on the application. Package type is likely a small outline package (SOP) or quad flat pack no-leads (QFN) for surface mount assembly. Further specifications would need to be derived from the official datasheet from Shanghai Belling.
