Product Summary

The A8290SETTR-T 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 A8290 requires few external components, with the boost switch and compensation circuitry integrated inside of the device.

Parametrics

A8290SETTR-T absolute maximum ratings: (1)Load Supply Voltage, VIN pin: 30 V; (2)Output Voltage, LNB, BFI, BFO pins: –1 to 33 V; (3)Logic Input Voltage, other pins : –0.3 to 7 V ; (4)Logic Output Voltage: –0.3 to 7 V; (5)Operating Ambient Temperature: –20 to 85°C ; (6)Junction Temperature: 150°C; (7)Storage Temperature : –55 to 150°C.

Features

A8290SETTR-T features: (1)LNB voltages (16 programmable levels) compatible with all common standards; (2)Tracking switch-mode power converter for lowest dissipation; (3)Integrated converter switches and current sensing; (4)Adjustable rise/fall time via external timing capacitor; (5)Auxiliary modulation input; (6)LNB overcurrent with timer; (7)Cable disconnect diagnostic.
