FEATURES  
DESCRIPTION  
The LM2694 Step Down Switching Regulator features  
all of the functions needed to implement a low cost,  
efficient, buck bias regulator capable of supplying  
0.6A to the load. This buck regulator contains an N-  
Channel Buck Switch, and is available in the 3 x 3

Integrated N-Channel Buck Switch  
Integrated Start-Up Regulator  
Input Voltage Range: 8V to 30V  
No Loop Compensation Required  
Ultra-Fast Transient Response  
thermally enhanced WSON-10 package and  
a
TSSOP-14 package. The feedback 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 results in a  
smooth transition from constant voltage to constant  
current mode when current limit is detected, reducing  
the frequency and output voltage, without the use of  
foldback. Additional features include: VCC under-  
voltage lockout, thermal shutdown, gate drive under-  
voltage lockout, and maximum duty cycle limiter.  
Operating Frequency Remains Constant with  
Load Current and Input Voltage Variations
