Product Summary

The LM5007MM/NOPB Step Down Switching Regulator features all of the functions needed to implement a low cost, efficient, Buck bias regulator. This device is capable of driving a 150 mA load current from a 9.5V to 95V input source. The switching frequency of the LM5007MM/NOPB can exceed 600 kHz, depending on the input and output voltages. The output voltage may be set from 2.5V to 85V. This high voltage regulator contains an N-Channel buck switch and internal startup regulator. The LM5007MM/NOPB is easy to implement and is provided in the MSOP-8 and the thermally enhanced LLP-8 packages. The LM5007MM/NOPB is a well suited alternative to a high voltage monolithic or discrete linear solution where the power loss becomes unacceptable. The regulator LM5009MM+ operation is based on a control scheme using an ON time inversely proportional to VIN. This feature allows the operating frequency to remain relatively constant over load and input voltage variations. The applications of the LM5007MM/NOPB are: Heat sink eliminator for classic linear regulator applications, 12V, 24V, 36V, and 48V rectified AC systems, 42V Automotive, Non-isolated AC mains charge coupled supplies, LED Current Source.
