ARG81300 Overview
The ARG81300 is a single-channel low-noise block regulator (LNBR). The ARG81300 consists of a monolithic boost converter followed by a low-drop linear regulator. It is specifically designed to provide the power and the interface signals to an LNB down converter via coaxial cable in satellite TV receiver systems.
ARG81300 Key Features
- Integrated boost MOSFET, current sensing, and pensation
- Stable with low-profile ceramic boost capacitors
- 704 kHz switching frequency for small low-cost
- S¯¯L¯¯E¯¯E¯¯P pin for ultralow power consumption mode
- Adjustable LNB output current limit (250 to 950 mA-)
- Covers wide array of application requirements
- Minimizes ponent sizing to fit each application
- For startup, reconfiguration, and continuous output
- Boost peak current limit scales with LNB current limit
- Optional temporary increased current limit (+25%)
