Key Features
- Adaptive on-time D-CAP2 control achieves fast load-transient response without an external compensation network, reducing design time and bill-of-materials components
- Wide 3 V to 28 V input voltage range covers 5 V USB-PD, 12 V ATX, and 24 V industrial rails in a single controller device
- Supports multi-phase parallel operation for output currents up to 40 A per phase, enabling scalable power delivery for server CPUs and high-current FPGAs in a compact 32-pin QFN package
Applications
TPS51610RHBR drives synchronous buck converters for server motherboard CPU and memory power stages where load currents exceed 20 A and transient response within 50 µs is required. Its 28 V input capability makes it suitable for telecom equipment powered from 24 V bus architectures that also supply 1.8 V and 1.0 V core rails. The device also targets industrial computing and storage systems that demand high-efficiency point-of-load regulation across a wide operating temperature range.

Frequently Asked Questions
What input voltage range does TPS51610RHBR support, and which power bus architectures does this cover?
TPS51610RHBR operates from a 3 V to 28 V input, covering the 5 V USB-PD bus, 12 V ATX desktop power bus, and 24 V industrial rack supply. This single device can regulate down to 1.0 V core rails in server and industrial computing platforms without requiring a pre-regulator stage, simplifying the power architecture and reducing total component count.
How does TPS51610RHBR's D-CAP2 adaptive on-time control simplify the output filter design compared to voltage-mode controllers?
D-CAP2 eliminates the external Type-III compensation network required by conventional voltage-mode controllers, saving 4 to 6 passive components per channel. The adaptive on-time modulation responds to output voltage deviations in one switching cycle, typically achieving a load-step transient recovery within 5 µs to 10 µs for a 10 A step change—performance comparable to current-mode controllers with full external compensation.
What QFN package dimensions does TPS51610RHBR use, and how does this affect thermal management in a high-current design?
TPS51610RHBR comes in a 32-pin QFN (5 mm × 5 mm body) with an exposed thermal pad. The exposed pad is soldered directly to the PCB ground plane, yielding a junction-to-board thermal resistance of approximately 10 °C/W. In a 12 V to 1.8 V conversion at 20 A output, the controller's own dissipation is typically under 300 mW, keeping junction temperature below 55 °C at 25 °C ambient with 2-layer copper pour.
