TPS65145 Description

Short technical summary and product information.

The Texas Instruments TPS65145 is a versatile power management IC designed to provide the necessary voltages for LCD and OLED displays. It integrates a positive charge pump converter (VO2), a negative regulated charge pump driver (VO3), and an auxiliary 3.3-V linear regulator controller.

This device operates with an input voltage range of 2.7 V to 5.8 V and features a fixed switching frequency of 1.6 MHz. The main output can reach up to 15 V with typical accuracy below 1%. It supports applications for displays ranging from 7 to 21 inches.

The TPS65145 includes internal soft-start and power-on sequencing features. It also offers fault detection for all outputs and thermal shutdown for system protection. The IC is available in 24-pin HTSSOP and 24-pin VQFN PowerPAD packages, suitable for various board space constraints.

Key electrical characteristics include a negative charge pump output voltage up to -2 V and a positive charge pump output voltage up to 30 V. The source driver voltage can range from 5 V to 15 V. The operating temperature range is -40°C to 85°C.
