- 4.5 V to 24 V input voltage range with 12 V nominal suits standard ATX, telecom 12 V, and industrial 24 V buses
- Voltage-mode PWM control with external compensation provides predictable, stable loop design for high-reliability systems
- Pb-free 28-pin TSSOP package (R-PDSO-G28) offers compact SMT footprint for high-density power stages
Applications
The TPS53124PW is designed to power dual-rail loads such as FPGA core and I/O supplies, DSP cores with separate analog and digital rails, and multi-voltage memory interfaces (DDR, QDR) from a single 12 V or industrial 24 V bus. Its adjustable output range of 0.76 V to 5.5 V enables it to generate sub-1 V core voltages alongside 3.3 V I/O rails in a single IC, reducing solution size in telecom line cards, network switches, and industrial automation controllers. The voltage-mode PWM architecture simplifies compensation design, making it suitable for production environments where loop stability over temperature and load variation is critical.

Frequently Asked Questions
What input voltage range does the TPS53124PW accept, and what output voltages can it regulate?
The TPS53124PW accepts an input voltage from 4.5 V to 24 V with a 12 V nominal bus, and produces two independently adjustable outputs ranging from 0.76 V to 5.5 V. This range covers sub-1 V FPGA core supplies, 1.2 V DDR memory, 1.8 V and 3.3 V I/O rails all within a single dual-controller IC.
How does the voltage-mode PWM control of TPS53124PW simplify loop compensation compared to current-mode controllers?
Voltage-mode PWM directly compares the output voltage error to a ramp waveform, so the compensation network has a straightforward single-pole/single-zero design without the subharmonic-stability concerns of peak current-mode control. Designers can calculate and verify the Type III compensator for each of the 2 output rails using standard small-signal models, reducing iteration cycles in high-reliability telecom and industrial power designs.
In which package does the TPS53124PW ship, and how many pins does it use?
The TPS53124PW ships in a 28-pin TSSOP (JESD-30 code R-PDSO-G28) with 0.65 mm pitch. The 28-pin count accommodates dual gate-drive outputs, dual feedback pins, dual soft-start pins, and power-good signals for two independent switching channels—keeping the footprint under 10 mm in length while providing full dual-controller functionality.
When is TPS53124PW preferable to using two single-channel controllers for a dual-rail FPGA power design?
Using TPS53124PW halves the IC count from 2 separate controllers to 1, saving at least 30–50 mm² of PCB area and reducing the number of decoupling capacitors needed. Shared sequencing and power-good logic can be coordinated through the single 28-pin package, simplifying FPGA startup rail sequencing—typically requiring core (0.9 V–1.0 V) to ramp before I/O (3.3 V)—without external sequencing logic.
