LP6220A 600mA LNB Power Supply & Control Voltage Regulator
■Designed for analog and digital satellite receivers/sat-TV, the LP6220A is a adjustable voltage regulator, specifically to provide the 14V/19V power supply and the 22kHz tone signaling to the LNB converter in the antenna dish or to the multi-switch box.
■LP6220A consists of a BOOST converter with a internal power MOS running at 1MHz switching frequency and a LDO regulator which with push-pull output stage generates clean 22-kHz tone signal superimposed at the output even at zero loading. The EXTM can accept a DiSEqC command and transfer it symmetrically to the output to meet DiSEqC 1.x protocol.
■Other features include over temperature protection and under-voltage lockout (UVLO). The LP6220A is available in a space saving ESOP-8 package.
●Features
■Low noise output to avoid sensitivity of Can Tuner and DISH’s LNA dropping down
■Single chip solution on 700mVpp 22KHz EXTM with 10μ s Trise/Tfall for less Transferring noise
■LNB Voltages (14V/19V) compatible with common standards, Push-pull output stage minimizes 14→19V and 19V→14V output transition times
■External 22KHz EXTM input
■1MHz Switch Frequency Boost
■Integrate Low Noise Linear Regulator
■Under Voltage Lockout
■Output Short-Circuit Protection
■Output Over-Current Protection
■Over-Temperature Protection
■Available in ESOP-8
■RoHS Compliant and Halogen Free
