XL6009  
400KHz 60V 4A Switching Current Boost / Buck-Boost / Inverting DC/ DC Converter  
Features  
General Description  
n Wide 5V to 32V Input Voltage Range  
n Positive or Negative Output Voltage  
Programming with a Single Feedback Pin  
n Current Mode Control Provides Excellent  
Transient Response  
The XL6009 regulator is a wide input range,  
current mode, DC/DC converter which is  
capable of generating either positive or  
negative output voltages. It can be configured  
as either a boost, flyback, SEPIC or inverting  
converter. The XL6009 built in N-channel  
power MOSFET and fixed frequency  
oscillator, current-mode architecture results in  
stable operation over a wide range of supply  
and output voltages.
