The ZLPM8010 is a power management and control solution for satellite set-top boxes (STBs). Based on an efficient boost converter the ZLPM8010 provides the power supply of up to 750mAand all the control signals required by a single port satellite Low Noise Block (LNB). The ZLPM8010 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 ZLPM8010 provides a high performing cost efficient solution.


  • Efficient boost converter providing an accurate adjustable power supplies LNBs
  • Operates from a single rail supply
  • Provides a protected output of up to 750mA
  • Adjustable current limit for system flexibility
  • Designed for stability with low power LNBs
  • Provides standard voltage / tone and DiSEqC™ control signals and allows for regional variations.
  • Internal 22kHz generator for DiSEqC™ control and traditional band switching
  • 22kHz maintains shape across all load conditions
  • Internal reliable tone detector for DiSEqC™ 2.0 systems
  • Control°C by I2C™ interface or independent logic control
  • Built in multiple diagnostics and protection for IC and LNB protection
  • Minimal external components for a simple, reliable and cost effective solution


  • Single / Dual Tuner Satellite Set-Top Boxes
  • Satellite PC Cards
  • TV’s with Integrated Satellite Tuners
  • Hybrid Set-Top Boxes
