Overview
The TPS51275RUKT is a Texas Instruments PMIC featuring two synchronous buck converters and two LDOs. It operates with switching frequencies of 300 kHz and 355 kHz. The device supports an input voltage range of 5 V to 24 V. Output configurations include controller outputs for the buck stages and fixed 3.3 V, 100 mA outputs for the LDOs. It functions within a temperature range of -40°C to +85°C and utilizes a 20-WQFN (3x3) package.
Feature Summary
- Integrates dual synchronous step-down controllers and dual low-dropout regulators in a single compact package.
- Utilizes D-CAP+ control architecture for stable operation across varying load and line conditions.
- Supports flexible output configuration through dedicated controller pins for external MOSFET drive.
Applications
- Portable electronics requiring multi-rail power distribution
- Industrial equipment with mixed logic and analog supply needs
- Communication infrastructure boards
Procurement Notes
Verify the specific suffix RUKT against official datasheets to confirm the tape-and-reel packaging format. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status via current manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when a combined solution for high-current digital rails and low-noise analog supplies is required. The integrated design reduces board space compared to discrete solutions. Verify that the 24 V maximum input voltage aligns with the system power source requirements.
Part Context
This part belongs to the TPS51275 family of power management ICs from Texas Instruments. It is categorized under PMICs combining linear and switching regulators. The device is designed for applications needing efficient power conversion with minimal external component count.
Replacement Considerations
The TPS51275CRUKT is a documented variant within the same product family. Verify pinout and electrical specifications against the specific datasheet revision before substitution.
