LM5009  
150 mA, 100V Step-Down Switching Regulator  
General Description  
Features  
n Integrated N-Channel MOSFET  
The LM5009 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 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 device is easy to  
implement and is provided in the MSOP-8 and the thermally  
enhanced LLP-8 packages. The LM5009 is a well suited  
alternative to a high voltage monolithic or discrete linear  
solution where the power loss becomes unacceptable. The  
n Guaranteed 150 mA output current capability  
n Ultra-Fast Transient Response  
n No loop compensation required  
n Vin feed forward provides constant operating frequency  
n Switching frequency can exceed 600 kHz  
n Highly efficient operation  
n 2% accurate 2.5V feedback from -40˚C to 125˚C  
n Internal startup regulator  
n Intelligent current limit protection  
n External shutdown control  
regulator’s operation is based on  
a hysteretic control  
n Thermal shutdown  
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 hyster-  
etic control requires no loop compensation, resulting in an  
ultra-fast transient response. An intelligent current limit is  
implemented with forced OFF time, which is inversely pro-  
portional to Vout. This scheme ensures short circuit protec-  
tion while providing minimum foldback. Other features in-  
clude: Thermal Shutdown, Vcc under-voltage lockout, Gate  
drive under-voltage lockout, and Maximum Duty Cycle lim-  
iter.  
n MSOP-8 and thermally enhanced LLP packages  
Typical Applications  
n Heat sink eliminator for classic linear regulator  
applications  
n 12V, 24V, 36V, and 48V rectified AC systems  
n 42V Automotive  
n Non-isolated AC mains charge coupled supplies  
n LED Current Source  
Package  
n MSOP - 8  
n LLP - 8 (4mm x 4mm) (Available Soon)
