1NN8186 INN8186 SOP8

توضیحات

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

Low noise output to avoid sensitivity of Can Tuner and DISH’s LNA dropping down

Noise <+/-40mV@300MHz BWL
Noise <+/-20mV@20MHz BWL
Single chip power solution with 650mV Vpp 22KHz tone control signal transferred to output
LNB Voltages (2 levels: 14.3V and 19.3V) compatible with common standards
External 22KHz tone input

Integrated DC DC boost converter and high efficiency (typ. 93%) with integrated Power Mosfet

Integrated low Noise Linear Regulator
Integrated power switches and current sensing
