  • Description

    JW®4005 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 JW4005 integrates a current mode boost converter followed by a tracking linear regulator. A high switching frequency is chosen to minimize the size of passive filtering components, further assisting in cost reduction. The tracking linear regulator protects the output against overload or short circuit.

    The JW4005 provides a number of features described in DiSEqC. For DiSEqC communications, the 22 KHz tone signal can be generated from external clock, all the way down to no-load.

    JW4005 is available in TSOT23-6 and ESOP8 packages.
