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 V_OUTRating

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

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.
