Overview
The TPS51225CRUKT is a Texas Instruments PMIC featuring two D-CAP synchronous buck controllers and two integrated LDOs. It operates within an input voltage range of 5.5 V to 24 V, supporting switching frequencies of 300 kHz and 355 kHz. The device provides regulated outputs including 5 V and 3.3 V LDOs with 100 mA current capability. Designed for surface mount installation in a 20-WQFN (3x3) package, it ensures reliable performance across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates dual synchronous step-down controllers with D-CAP control mode
- Includes two low-dropout regulators providing 5 V and 3.3 V outputs
- Supports wide input voltage range up to 24 V for flexible power architectures
Applications
- Portable laptop debugging and maintenance power supplies
- Multi-rail server and workstation power distribution networks
- Embedded systems requiring combined DC-DC and LDO regulation
Procurement Notes
Verify the specific suffix 'CRUKT' against the official datasheet to confirm the presence of both buck controllers and LDOs, as other variants may differ. Ensure the WQFN-20 package matches your PCB footprint requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning.
Selection Notes
Select this component when a single IC solution is required to generate multiple voltage rails efficiently. It is suitable for designs needing synchronized buck conversion alongside stable LDO outputs for sensitive logic. Consider the thermal performance of the exposed pad in high-current applications.
Part Context
This part belongs to the TPS51225 family of power management integrated circuits from Texas Instruments. The series combines switching controller functionality with linear regulator capabilities to simplify board space and reduce component count in complex power delivery systems.
Replacement Considerations
Public confirmed substitute part numbers include TPS51225BRUKT and TPS51225RUKR. Verify pin compatibility and electrical specifications before substitution.
