Product details

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.

Features

High Efficiency: Up to 90%.
Low noise output to avoid sensitivity of Can Tuner and DISH’s LNA dropping down.
Noise 40mV@20MHz BWL.
Single chip solution on 650mVpp.
22kHz TONE with 10µs Trise/Tfall for less Transferring noise.
LNB Voltages (2 levels: 14V and 19V) compatible with common standards, Push-pull output stage minimizes 14V → 19V and 19V → 14V output transition times.
External 22kHz TONE input.
Integrated DC/DC BOOST converter and high efficiency.
