The A8307 single wire multiswitch regulator (SWMR) is a monolithic linear and switching voltage regulator, specifically designed to provide power to single wire multiswitches in satellite TV systems via coaxial cable. The A8307 requires few external components, with the boost switch and compensation circuitry integrated inside of the device.
The integrated boost switch has been optimized to minimize both switching and static losses. To further enhance efficiency and thermal performance, the voltage drop across the tracking regulator is minimized.
A comprehensive set of fault registers are provided, which comply with all the common standards, including: overcurrent, thermal shutdown, undervoltage, and power not good. Furthermore, design methodology and structure ensure the highest level of robustness against transients and component failures. The device uses a 2-wire bidirectional serial interface, compatible with the I2C™ standard, that operates up to 400 kHz.
The A8307 is provided in a 4 × 4 mm QFN package with exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.
