TMI8037
FEATURES
- High Efficiency: Up to 90%
- Low noise output to avoid sensitivity of Can
Tuner and DISH’s LNA dropping down
- Noise 40m V@20MHz BWL
- Single chip solution on 650m Vpp
- 22k Hz TONE with 10µs Trise/Tfall for less
Transferring noise
- LNB Voltages (2 levels: 14V and 19V) patible with mon standards, Push-pull output stage minimizes 14V → 19V and 19V → 14V output transition times
- External 22k Hz TONE input
- Integrated DC/DC BOOST converter and high efficiency (typ. 87%) with integrated Power MOSFET
- 1.0MHz Switch Frequency BOOST
- Integrated low Noise Linear Regulator
- 5.0V, 3.3V, 2.5V, 1.8V, logic patible
- Internal Short, OCP, OTP protection
- ESOP8 package
APPLICATIONS
- LNB Power supply for DVB-S/S2/ABS
- Digital STB
- Satellite TV cards
GENERAL 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...
