LM25010/LM25010Q  
42V, 1.0A Step-Down Switching Regulator  
General Description  
Features  
The LM25010 features all the functions needed to implement  
a low cost, efficient, buck regulator capable of supplying in  
excess of 1A load current. This high voltage regulator inte-  
grates an N-Channel Buck Switch, and is available in ther-  
mally enhanced LLP-10 and TSSOP-14EP packages. The  
constant on-time regulation scheme requires no loop com-  
pensation resulting in fast load transient response and sim-  
plified circuit implementation. The operating frequency re-  
mains constant with line and load variations due to the inverse  
relationship between the input voltage and the on-time. The  
valley current limit detection is set at 1.25A. Additional fea-  
tures include: VCC under-voltage lock-out, thermal shutdown,  
gate drive under-voltage lock-out, and maximum duty cycle  
limiter.  
Wide 6V to 42V Input Voltage Range  
Valley Current Limiting At 1.25A  
Programmable Switching Frequency Up To 1 MHz  
Integrated N-Channel Buck Switch  
Integrated High Voltage Bias Regulator  
No Loop Compensation Required  
Ultra-Fast Transient Response  
Nearly Constant Operating Frequency With Line and Load  
Variations  
Adjustable Output Voltage  
2.5V, ±2% Feedback Reference  
Programmable Soft-Start  
Thermal shutdown  
LM25010Q is AEC-Q100 Grade 1 & 0 qualified  
Typical Applications  
Non-Isolated Telecommunications Regulator  
Secondary Side Post Regulator  
Automotive Electronics  
Package  
LLP-10 (4 mm x 4 mm)  
TSSOP-14EP  
Both Packages Have Exposed Thermal Pad For Improved  
Heat Dissipation  
Basic Step-Down Regulator
