The TPS65140PWP from Texas Instruments is a specialized power management IC designed for LCD and OLED display applications. This device integrates a 4-channel LCD bias solution with a fully integrated positive charge pump, a 3.3V LDO controller, and a 1.6A minimum boost current limit with fault detection.
Key electrical specifications include an input voltage range of 2.7V to 5.8V and a fixed switching frequency of 1.6MHz. It provides three independent adjustable outputs, with the main output capable of reaching up to 15V. The device also features a negative regulated charge pump driver (VO2) and a positive charge pump converter (VO3), along with an auxiliary 3.3V linear regulator controller.
Designed for applications such as LCD monitors and notebook displays, the TPS65140PWP operates within an ambient temperature range of -40°C to 85°C. It is available in a 24-pin HTSSOP package, measuring 7.8 mm x 6.4 mm, and a 24-pin VQFN package, measuring 4 mm x 4 mm. The IC includes internal soft-start and power-on sequencing, along with fault detection for all outputs and thermal shutdown for system protection.
