LM2694  
30V, 600 mA Step Down Switching Regulator  
n No loop compensation required  
n Ultra-Fast transient response  
n Operating frequency remains constant with load current  
and input voltage variations  
n Maximum Duty Cycle Limited During Start-Up  
n Adjustable output voltage  
n Valley Current Limit At 0.6A  
n Maximum switching frequency: 1 MHz  
n Precision internal reference  
n Low bias current  
n Highly efficient operation  
General 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 thermally enhanced LLP-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 operat-  
ing 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 fea-  
tures include: VCC under-voltage lockout, thermal shut-  
down, gate drive under-voltage lockout, and maximum duty  
cycle limiter.  
n Thermal shutdown  
Typical Applications  
n High Efficiency Point-Of-Load (POL) Regulator  
n Non-Isolated Telecommunication Buck Regulator  
n Secondary High Voltage Post Regulator
