LM25010  
42V, 1.0A Step-Down Switching Regulator  
General Description  
Features  
n Wide 6V to 42V Input Voltage Range  
n Valley Current Limiting At 1.25A  
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. Addi-  
tional features include: VCC under-voltage lock-out, thermal  
shutdown, gate drive under-voltage lock-out, and maximum  
duty cycle limiter.  
n Programmable Switching Frequency Up To 1 MHz  
n Integrated N-Channel Buck Switch  
n Integrated High Voltage Bias Regulator  
n No Loop Compensation Required  
n Ultra-Fast Transient Response  
n Nearly Constant Operating Frequency With Line and  
Load Variations  
n Adjustable Output Voltage  
n 2.5V, 2% Feedback Reference  
n Programmable Soft-Start  
n Thermal shutdown  
Typical Applications
