LM5010A  
High Voltage 1A Step Down Switching Regulator  
General Description  
Features  
n Wide 6V to 75V Input Voltage Range  
n Valley Current Limiting At 1.25A  
The LM5010A Step Down Switching Regulator is an en-  
hanced 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 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 LLP-10 and  
TSSOP-14EP 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.  
n Programmable Switching Frequency Up To 1 MHz  
n Integrated 80V 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
