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 ant
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.
