Product Specification

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 two LNB down converters via coaxial cables. The WT20-1809 requires few external components, with the boost switches and compensation circuitry integrated inside of the device. A high switching frequency is chosen to minimize the size of the passive filtering components, further assisting in cost reduction. The high level of component integration ensures extremely low noise and ripple figures. For DiSEqCTM communications, a tone control pin is provided to gate the internally-generated 22 kHz tone on-and-off.

A comprehensive set of fault registers are provided which, comply with all the common standards, including: overcurrent, thermal shutdown, under-voltage, and power not good.

The device uses a 2-wire bidirectional serial interface, compatible with the I2C? standard, which operates up to 400 kHz.
A SLEEP pin is available to maximize power savings and to quickly shut down the device if needed, without I2C? control.

The WT20-1809 is supplied in a lead (Pb) free package.
