Key Features
- 6 A continuous output current with integrated high-side and low-side MOSFETs eliminates external switching transistors and simplifies PCB layout
- Wide 4.5 V to 17 V input range covers industrial 12 V bus and distributed power architectures with a single device
- Current-mode PWM control provides fast transient response and inherent cycle-by-cycle current limiting for load protection in point-of-load converters
Applications
The TPS54622RHLT serves as a high-efficiency point-of-load regulator in telecom line cards, network switches, and industrial control systems powered from a 12 V bus. Its 6 A current capability and 4.5 V to 17 V input range also make it suitable for FPGA core and I/O supply rails where fast transient response is critical. Server and storage systems benefit from its compact 14-pin VQFN footprint and fully integrated switching stage that simplifies thermal design.

Frequently Asked Questions
How much continuous load current can the TPS54622RHLT deliver, and what input voltage range does it support?
The TPS54622RHLT is rated for 6 A continuous output current with an input voltage range of 4.5 V to 17 V. This combination makes it suitable for 12 V industrial bus applications requiring high-current point-of-load conversion to 1.0 V, 1.8 V, 2.5 V, or 3.3 V processor and FPGA supply rails.
What package does the TPS54622RHLT use, and how does it affect heat dissipation in a dense PCB layout?
The TPS54622RHLT comes in a 14-pin VQFN (QFN) package with an exposed thermal pad on the bottom, which enables efficient heat transfer to the PCB copper plane. At 6 A output, the integrated MOSFETs dissipate roughly 500 mW to 1 W; the exposed pad keeps junction temperature within limits without bulky heatsinks, saving space in 12 V point-of-load designs.
Why is current-mode PWM control important for FPGA core supply designs using the TPS54622RHLT?
Current-mode PWM control gives the TPS54622RHLT inherently fast transient response by reacting to inductor current changes within a single switching cycle. For an FPGA core rail at 1.0 V, a sudden 3 A load step occurs in under 1 µs; current-mode architecture limits output voltage deviation to typically less than 50 mV, keeping the FPGA's supply well within its ±5% regulation window.
Can the TPS54622RHLT replace a discrete MOSFET plus controller solution in a 12 V to 3.3 V conversion stage?
Yes. The TPS54622RHLT integrates both high-side and low-side N-channel MOSFETs rated for 6 A alongside the PWM controller, replacing at least 2 external FETs, a gate driver, and associated bootstrap and gate resistors. This reduces the total component count by roughly 8 to 12 parts, shrinks board area, and improves reliability compared to a discrete 12 V to 3.3 V synchronous buck implementation.
