The A8304 requires few external components, with the boost switch and compensation circuitry integrated into the device. The 704 kHz switching frequency and user-controlled output current limit minimize the size of the passive filtering components. An I2C-compatible interface provides control capabilities for complex system requirements, as well as diagnostic information for system fault reporting. A “sleep” pin is also available to maximize power savings and to quickly shut down the device if required, without using I2C control. New control features for output source and sink current are also incorporated. The A8304SESTR-T is provided in a 3x3mm QFN package with exposed pad for thermal dissipation. It is lead (Pb) free, with 100% matt tin leadframe plating.
