Allegro MicroSystems A8302 Supply & Control Voltage Regulators
Allegro MicroSystems A8302 Supply and Control Voltage Regulators are dual-channel low-noise block converter regulators. The A8302 has a monolithic linear and switching voltage regulator designed to provide power and interface signals to an LNB down converter. It uses a coaxial cable in satellite TV receivers systems. The A8302 requires a few external components, with the boost switch and compensation circuitry integrated inside the device.Features
- Integrated boost MOSFET, current sensing, and compensation
- Configurable boost capacitor option through I2C™ control register ceramic or electrolytic
- Two switching frequency settings are programmable through the I2C™ control register (563 kHz and 939 kHz)
- Adjustable LNB output current limit from 250 to 950mA
- Covers a wide array of application requirements
- Minimizes component sizing to fit each application
- For a startup, reconfiguration and continuous output
- Optional temporary increased current limit (+25%)
- Internal gate drives output BFGATEx for bypass FET used in DiSEqC™ applications
