About this product
The STI8036 is a monolithic boost converter and linear regulator in an SOP-8 package that powers the LNB of a satellite dish from a receiver. It switches its output between 14V and 19V to select LNB polarity and generates the 22kHz tone used for band switching. It is used in satellite receivers and LNB power supply designs.

Frequently asked questions
How are the 14V/19V and 22kHz tone used?
The 14V and 19V levels select the LNB polarity, and the 22kHz tone selects the band. The exact pin-level control method is described in the datasheet.
Is this a ready-made power module?
No. It is a bare IC in an SOP-8 package and needs a PCB with the external components specified in its datasheet to work.
