response and simple circuit implementation. The  
operating frequency remains nearly constant with line  
variations due to the inverse relationship between the  
input voltage and the ON-time. The operating  
frequency can be externally programmed up to  
1 MHz. Protection features include VCC undervoltage  
lockout (UVLO), output overvoltage protection,  
thermal shutdown, and gate drive UVLO. The  
LM3102/-Q1 is available in the thermally enhanced  
HTSSOP-20 package, and LM3102 is also available  
in a DSBGA low-profile chip-scale package with  
reduced output current.
