A8296SESTR-T QFN16 A8296 A8296SESTR
Single LNB Supply And Control Voltage Regulator
Intended for analog and digital satellite receivers, this single low noise block converter regulator (LNBR) is a monolithic linear and switching voltage regulator, specifically designed to provide the power and the interface signals to an LNB down converter via coaxial cable. The A8296 requires few external components, with the boost switch and compensation circuitry integrated inside of the device.
The A8296 has been designed for high efficiency, utilizing the Allegro® advanced BCD process. The integrated boost switch has been optimized to minimize both switching and static losses. To further enhance efficiency, the voltage drop across the tracking regulator has been minimized.
For DiSEqC™ communications, a tone control pin is provided to gate the internally-generated 22 kHz tone on-and-off.
