Description
The ZLPM8011 is a power management and control solution for satellite set-top boxes (STBs). Based on an efficient boost converter the ZLPM8011 provides the power supply of upto 450mA and all the control signals required by a single port satellite Low Noise Block (LNB). The ZLPM8011 includes an accurate 22kHz tone generator to provide DiSEqC™ control words or continuous tone for band switching control. To provide a reliable DiSEqC™ 2.0 solution the IC includes a DiSEqC™ detector with unwanted signal rejection. Control°C by I2C™ or logic inputs and with the minimal external components the ZLPM8011 provides a high performing cost efficient solution.
