The LM25010 features all the functions needed to  
–
Device Temperature Grade 0: –40°C to 150°C  
Ambient Operating Temperature Range  
implement  
a
low-cost, efficient, buck regulator  
capable of supplying in excess of 1-A load current.  
This high voltage regulator integrates an N-Channel  
Buck Switch, and is available in thermally enhanced  
10-pin WSON and 14-pin HTSSOP packages. The  
constant ON-time regulation scheme requires no loop  
compensation resulting in fast load transient  
response and simplified circuit implementation. The  
operating frequency remains 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 1.25 A.  
Additional features include: VCC undervoltage  
lockout, thermal shutdown, gate drive undervoltage  
lockout, and maximum duty cycle limiter.
