Input Voltage Range: 8V to 75V  
Valley Current Limit At 1.25A  
The LM5010 Step Down Switching Regulator features all the  
functions needed to implement a low cost, efficient, buck  
bias regulator capable of supplying in excess of 1A load  
current. This high voltage regulator contains an N-Channel  
Buck Switch, and is available in thermally enhanced LLP-10  
and TSSOP-14EP packages. The hysteretic regulation  
scheme requires no loop compensation, results in fast load  
transient response, and simplifies 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  
lockout, thermal shutdown, gate drive under-voltage lockout,  
and maximum duty cycle limiter.  
Switching Frequency Can Exceed 1 MHz
