Product details
TPS51225BRUKR is commonly used where efficient dual-rail conversion, standby/bias power, and board-level supervision are needed in a small package without placing all switching power dissipation inside the controller IC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Dual synchronous step-down controller for 5V and 3.3V system rails. |
| Power Stage | Uses external MOSFETs, inductors, and capacitors to set current capability and thermal performance. |
| Target Outputs | Notebook or embedded system 5V and 3.3V buck rails. |
| LDO / Bias Support | Integrated LDO or bias functions support standby and controller supply rails. |
| Control | Enable, soft-start, feedback, compensation, and power-good functions support system sequencing. |
| Package | 20-pin WQFN RUK package for TPS51225BRUKR. |
| Application Area | Notebook, embedded computing, motherboard, and industrial PC power systems. |
| Design Value | Controller architecture supports scalable current and efficient system rail conversion. |
Pinout & Package
The TPS51225BRUKR pinout includes controller supply pins, high-side and low-side gate-drive pins, switch-node sense pins, feedback and compensation pins, enable controls, LDO/bias pins, and status outputs.
For PCB design, gate-drive loops and switching-current paths should be short, MOSFETs and input capacitors should be placed around the power stage, and feedback/compensation traces should avoid switch-node noise.
| Pin / Function | PCB Design and Circuit Role |
|---|---|
| VCC / VIN | Controller and gate-drive supply input. |
| UGATE / LGATE | Gate-drive outputs for external MOSFETs. |
| PHASE / SW | Switch-node sensing connection for buck control. |
| FB / COMP | Feedback and compensation nodes for loop regulation. |
| EN / MODE | Enable or operating-mode control pins. |
| LDO / VREG | Bias or linear regulator support pins. |
| PGOOD | Power-good status output for system supervision. |
| GND | Controller ground reference requiring low-noise layout. |
Key Features
