Descriptions
Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the INN8186 is a monolithic voltage regulator and interface IC, packaged in SOP8EP, specifically designed to provide the 14/19V power supply with high efficiency and the 22k Hz tone signaling to the LNB down-converter in the antenna dish or to the multi-switch box.
INN8186 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 pact with low external ponent count
The external modulation input (TONE pin) can accept a tome modulated Di SEq C mand and transfer it symmetrically to the output to meet Di SEq C...
