DESCRIPTION  
•
•
•
•
•
Integrated 80V N-Channel Buck Switch  
Integrated High Voltage Bias Regulator  
No Loop Compensation Required  
Ultra-Fast Transient Response  
The LM5010A Step-Down Switching Regulator is an  
enhanced version of the LM5010 with the input  
operating range extended to 6V minimum. The  
LM5010A features all the functions needed to  
implement  
a low cost, efficient, buck regulator  
Nearly Constant Operating Frequency With  
Line and Load Variations  
capable of supplying in excess of 1A load current.  
This high voltage regulator integrates an N-Channel  
Buck Switch, and is available in thermally enhanced  
WSON-10 and HTSSOP-14 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 1.25A. Additional  
features include: VCC under-voltage lock-out, thermal  
shutdown, gate drive under-voltage lock-out, and  
maximum duty cycle limiter.
