MP8124GD-P

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