MP8124  
500mA LNB Power Supply  
and Control Regulator  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP8124 is a highly integrated voltage  
regulator designed to provide efficient, low-  
noise power and interface signals to the low-  
noise block (LNB) of a satellite receiver. It  
provides a 22kHz tone signal output, which is  
compatible with DiSEqC 1.x.  
Compatible with DiSEqC 1.x  
600mA Accurate Current Limit  
8V to 14V Input Voltage  
40V VOUT Rating  
Low-Noise LDO Output  
High Efficiency at Light Load: >85% at a  
40mA Load  
High Frequency for Small Component Sizes  
Built-In 22kHz Signal Shaper  
Selectable Output Voltage  
Over-Current Protection (OCP) Short-Circuit  
Protection (SCP)  
Boost Over-Voltage Protection (OVP)  
Over-Temperature Protection (OTP)  
The MP8124 integrates a current-mode boost  
regulator followed by a tracking linear regulator.  
Also, it has output voltage selection and a  
22kHz tone shaper from an external signal.  
The boost regulator provides a clean power  
source, which is 1V higher than the final output  
voltage while the tracking linear regulator  
protects the output against overloads and  
shorts.  
Available in  
Package  
a
QFN-14 (2mmx3mm)  
Full protection features include over-current  
protection (OCP), short-circuit protection (SCP),  
boost over-voltage protection (OVP), and over-  
temperature protection (OTP), offering a simple  
solution with a low component count and high  
efficiency.  
APPLICATIONS  
LNB Power Supply and Control for Satellite  
Set-Top Boxes  
TV Satellite Receivers  
PC Card Satellite Receivers  
The MP8124 is available in a 14-pin QFN  
(2mmx3mm) package.  
All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
