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 22kHz 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 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.

Notes:
1) Exposed pad has to be connected to GA and GP ground shortly;
2) C4 should be very close to VSW pin and GP pin, which can reduce noise largely
3) C1 should be very close to VIN pin
4) Co5 should be very close to VLNB pin
5) R1 (5.1Kohm, 1206) is only for no loadings 22KHz Tone waveform due to that Ds2 diode
switches off sinking current into VLNB pin.
