FEATURES  
DESCRIPTION  
The TPS65133 is designed to drive LCD displays  
requiring a positive and negative supply rail. It may  
also be used as a general ±5 V supply for operational  
amplifiers or other devices requiring similar positive  
and negative supplies. The device integrates a boost  
converter and an inverting buck-boost converter  
suitable for battery operated products.
