FEATURES  
DESCRIPTION  
The LM22670 switching regulator provides all of the  
functions necessary to implement an efficient high  
voltage step-down (buck) regulator using a minimum  
of external components. This easy to use regulator

incorporates  
a 42V N-channel MOSFET switch  
capable of providing up to 3A of load current.  
Excellent line and load regulation along with high  
efficiency (>90%) are featured. Voltage mode control  
offers short minimum on-time, allowing the widest  
ratio between input and output voltages. Internal loop  
compensation means that the user is free from the  
tedious task of calculating the loop compensation  
components. Fixed 5V output and adjustable output  
voltage options are available. The default switching  
frequency is set at 500 kHz allowing for small  
external components and good transient response. In  
addition, the frequency can be adjusted over a range  
of 200 kHz to 1MHz with a single external resistor.  
The internal oscillator can be synchronized to a  
system clock or to the oscillator of another regulator.  
A precision enable input allows simplification of  
regulator control and system power sequencing. In  
shutdown mode the regulator draws only 25 µA (typ.).  
Built in soft-start (500µs, typ) saves external  
components. The LM22670 also has built in thermal  
shutdown, and current limiting to protect against  
accidental overloads.

family.  
The  
SIMPLE  
SWITCHER concept provides for an easy to use  
complete design using a minimum number of external  
components and the TI WEBENCH design tool. TI's  
WEBENCH tool includes features such as external  
component calculation, electrical simulation, thermal  
simulation, and Build-It boards for easy design-in.
