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 down converter in the antenna dish or to the multi-switch box. TMI8037 consists of a BOOST converter and a low-noise linear regulator along with the circuitry required for TONE injection and pin controllable interface. The device makes the total LNB supply design simple, efficient and compact with low external component count.

The external modulation input (TONE pin) can accept a tome modulated DiSEqC command and transfer it symmetrically to the output to meet DiSEqC 1.x protocol.
