TMI8037 Description
Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the TMI8037 is a monolithic voltage regulator and interface IC, packaged in ESOP8, specifically designed to provide the 14V/19V power supply with high efficiency and the 22kHz TONE signaling to the LNB downconverter in the antenna dish or to the multi-switch box. TMI8037 consists of a BOOST converter and a low-noise linear regulator along with...
