Allegro Microsystems offers single and dual LNB supply and control voltage regulator ICs
Allegro Microsystems
A8295, A8297 and A8298
Allegro Microsystems has introduced the A8295, A8297 and A8298 single and dual low-noise block (LNB) supply and control voltage regulator ICs, which are designed for use in satellite receivers in set-top boxes and LCD television sets.
The devices are fully integrated linear and switching voltage regulators, 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 are intended 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 associated costs.
