FEATURES  
DESCRIPTION  
The LM34910C Step Down Switching Regulator  
features all of the functions needed to implement a  
low cost, efficient, buck bias regulator capable of  
supplying 1.25A to the load. This buck regulator  
contains a 55V N-Channel Buck Switch, and is  
available in the thermally enhanced WSON-10  
package. 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  
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.
