Frequently Asked Questions
What is the input and output voltage range of the TPS54623RHLR?
The TPS54623RHLR accepts an input voltage from 4.5V to 17V, making it compatible with 5V and 12V bus rails. The output voltage is adjustable down to 0.8V via an external resistor divider, allowing it to supply a wide range of core logic voltages such as 1.0V, 1.2V, 1.8V, 2.5V, and 3.3V.
What is the maximum continuous output current of the TPS54623RHLR?
The TPS54623RHLR is rated for 6A continuous output current. It integrates both high-side and low-side N-channel MOSFETs internally, eliminating the need for external switching transistors and simplifying the overall power stage design.
What control topology does the TPS54623RHLR use?
It uses current-mode pulse width modulation (PWM) control. Current-mode control provides inherent cycle-by-cycle current limiting, simplified loop compensation, and fast transient response compared to voltage-mode alternatives, making it easier to stabilize across varying load conditions.
What package does the TPS54623RHLR come in and what are the PCB considerations?
The TPS54623RHLR is housed in a 14-pin VQFN (QFN) package (JESD-30 code S-PQCC-N14) with an exposed thermal pad for heat dissipation. The compact footprint suits high-density PCB designs. Proper thermal via placement under the exposed pad is recommended to meet the 6A current rating at elevated temperatures.
What are common applications for the TPS54623RHLR?
Typical applications include point-of-load regulators in telecom line cards, industrial control boards, network switches, and embedded computing modules. It is frequently used to power FPGAs, DSPs, microcontrollers, and memory arrays that require tightly regulated sub-3.3V supplies from a 5V or 12V input bus.
