Overview
The TPS51123ARGET is a PMIC featuring two synchronous buck converters and two low-dropout linear regulators. It operates with an input voltage range of 5.5V to 28V and utilizes D-CAP topology at a switching frequency of 460kHz. The device integrates two controller outputs for the buck stages and provides fixed 3.3V/100mA LDO outputs. It is housed in a 24-VQFN (4x4) package with exposed pad, rated for operation between -40°C and +85°C.
Feature Summary
- Integrates dual synchronous step-down controllers and dual linear regulators in a single compact package
- Utilizes D-CAP control mode for stable operation across varying load conditions
- Supports wide input voltage ranges suitable for industrial and computing applications
Applications
- Industrial equipment power distribution
- Computing system bias supplies
- Telecommunications infrastructure power management
Procurement Notes
Verify the specific suffix 'ARGET' against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 24-VQFN footprint aligns with your PCB layout constraints. Confirm RoHS compliance status if required by your assembly standards.
Selection Notes
Select this component when a combined solution for high-current buck conversion and precise analog supply regulation is needed. The integrated nature reduces board space compared to discrete solutions. Consider the 460kHz frequency for balancing efficiency and passive component size.
Part Context
This part belongs to Texas Instruments' TPS5112x family of multi-output power management ICs. These devices are designed to simplify power architecture by combining multiple regulator types. The TPS51123 variant specifically targets applications requiring both switched-mode and linear regulation capabilities.
Replacement Considerations
Check for TPS51123ARGER or other suffix variations within the same series for identical functionality with different packaging options. Verify compatibility with existing thermal designs when substituting.
