RT5070

Single Output LNB Supply and Control Voltage Regulator

Features

General Description

 Wide Input Supply Voltage Range : 8V to 16V

 Output Current Limit of 550mA with 45ms Timer

 Low Noise LNB Output Voltage (13.3V and 18.3V

by SEL Pin)

The RT5070 is a highly integrated voltage regulator

and interface IC, specifically design for supplying

power and control signals from advanced satellite

set-top box (STB) modules to the LNB down-converter

in the antenna dish or to the multi-switch box.

 ±3% High Accuracy for 0mA to 500mA Current

Output

The device is consists of the independent current-mode

boost controller and low dropout linear regulator for the

LNB power.

 Push-Pull Output Stage Minimizes 13.3V to

18.3V and 18.3V to 13.3V Output Transition Time

 Output Short Circuit Protection

 Over-Temperature Protection

The RT5070 has fault protection (over-current,

over-temperature and under-voltage lockout).

Applications

 LNB Power Supply and Control for Satellite Set-Top

The RT5070 are available in a SOP-8 (Exposed Pad)

package to achieve optimized solution for thermal

dissipation.

Box

 Analog and Digital Satellite Receivers/Satellite TV,
