描述 Description

The ZLPM8012 is a power management and control solution for satellite set-top boxes (STBs). Based on an efficient boost converter the ZLPM8012 provides the power supply of upto 450mA and all the control signals required by a single port satellite Low Noise Block (LNB). The ZLPM8012 includes an accurate 22kHz tone generator to provide DiSEqC? control words or continuous tone for band switching control. Control°C by I2C? and with the minimal external components the ZLPM8012 provides a high performing cost efficient solution.
