The TPS75003RHLT with Power Management Specialised - PMIC Integ 3-Supply Power Mngmnt IC is an adjustable voltage regulator specifically designed by Texas Instruments. It is a low-cost DC-DC converter module that combines Power Management Specialised (PMIC) with an integrative three-supply power management IC, allowing the user to dynamically adjust power output depending on application and load requirements. Its PMIC allows the user to create a multi-supply voltage rail to help power multiple components within the system, and its 3-Supply PMIC integrates an adjustable-frequency low voltage buck converter, a high voltage switch, a step-down converter, and a low-dropout regulator. Additionally, the TPS75003RHLT has built-in fault control and protection features that ensure safe and reliable operation. It is designed for use with microcontrollers, consumer electronics, automotive applications, and medical equipment.
