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.
APPLICATIONS
• LCD Bias
• Active Matrix OLED
• Operational Amplifier Supply
• General ±5 V Power Supply
