JW4002 - LNB Power Supply and Control Voltage Regulator

Datasheet Summary

Description

JW4002 is a monolithic linear and switching voltage regulator, specially designed to provide efficient, low noise power to Satellite receiver’s RF LNB (Low Noise Block) converter via coaxial cable.

The JW4002 integrates a current mode boost converter followed by a tracking linear regulator.

Features

DiSEqC 1.x Compatibility Up to 550mA Continuous Output Current 8V to 14V Input Voltage Tracking Switch-Mode Power Converter for Lowest Power Dissipation, High Efficiency Boost Converter with Internal Switch Low Noise Linear Regulator Output 1V Line Drop Compensation External Input 22KHz Tone Output Short Circuit Robust Input Voltage UVLO Protection Over Temperature Protection.
