Applications
The TPS59610RHBR is designed for DC-DC switching power conversion in industrial automation, telecom infrastructure, and server power supplies where a wide 3 V to 28 V input range must be down-converted to a regulated output voltage with high efficiency. Its external-MOSFET controller topology allows designers to tailor the switch current rating and package for the specific output power requirement, from a few watts up to tens of watts. The 32-pin QFN package with thermal pad suits multi-layer PCBs in networking equipment, motor drives, and embedded computing modules requiring reliable, high-efficiency step-down conversion.

Frequently Asked Questions
What input voltage range does TPS59610RHBR support, and which industrial supply rails is it compatible with?
The TPS59610RHBR operates with input voltages from 3 V to 28 V, making it directly compatible with 5 V USB power rails, 12 V desktop supply rails, and 24 V industrial bus voltages. This wide range enables a single design to support multiple power supply standards without changing the controller IC, reducing component qualification effort.
How does TPS59610RHBR as an external-MOSFET controller differ from an integrated-switch buck converter?
As a switching controller without an integrated power MOSFET, the TPS59610RHBR drives external N-channel or P-channel MOSFETs, allowing the designer to select switch devices optimised for the target current level—from 1 A to tens of amperes. This flexibility is valuable in applications above 5 A or 10 A where an integrated-switch converter would require expensive high-current packaging, while the 32-pin QFN controller stays cool by offloading conduction losses to the external FETs.
For a 24 V industrial panel power supply, how does TPS59610RHBR help maintain regulation during input voltage transients?
The TPS59610RHBR is rated for 28 V maximum input, giving 4 V of headroom above a nominal 24 V rail. This margin absorbs inductive load-switching transients and input-line spikes common in industrial environments. The switching controller's closed-loop regulation immediately adjusts the duty cycle to maintain the set output voltage when the 24 V bus sags or surges within the 3 V to 28 V window.
What thermal advantage does the 32-pin QFN package of TPS59610RHBR provide in a compact power supply design?
The 32-pin QFN package includes an exposed thermal pad on the underside that solders directly to a PCB copper pour or thermal via array. This low-thermal-resistance path—typically 1°C/W to 3°C/W junction-to-board—allows the controller to dissipate gate-drive losses without a bulky heatsink, keeping the junction temperature well below the maximum rated value even at high switching frequencies above 500 kHz in a compact PCB form factor.
