The new devices are fully integrated linear and switching voltage regulators
that are specifically designed to provide the power and the interface
signals to an LNB down-converter via coaxial cable. They offer increased
internal protection and robustness, an integrated boost MOSFET, current
sensing, and compensation, all of which combine to simplify users’ designs,
minimise the need for external components, and reduce PCB size.
All the devices have a reduced supply current to save energy, built-in
diagnostic capabilities, and a resistor-programmed output current limit to
minimise the boost inductor/diode size and costs.
The A8295SESTR-T and the A8298SESTR-T are available in a 4 × 4 mm
TQFN/MLP-20 package, while the A8297SETTR-T is available in a 5 × 5 mm
TQFN/MLP-28 package.
