| High Light | 17V Input DC-DC Power Supply Chip ，6A Output Synchronous Step-down Converter ，Synchronous Step-down Conversion TPS54622RHLREP | ||
The TPS54622-EP device adopts a thermally enhanced 3.5mm × 3.5mmVQFN package and is a fully functional 17V, 6A synchronous step-down converter. This device features high efficiency and integrates high-side and low-side MOSFETs. It has been optimized to achieve a compact design. By adopting current-mode control to reduce the number of components and choosing a high switching frequency to shrink the inductor size, further space can be saved. The output voltage start ramp is controlled by the SS/TR pin, which supports both independent power supply operation and tracking mode. In addition, correctly configuring the enable and drain power supply good pins can also achieve power sequencing. The cycle-by-cycle current limiting of the high-side FET can protect the device in case of overload and prevent current runaway through the low-side pull-up current limiting, enhancing the limiting effect. In addition, a low-side potting current limit that can turn off the low-side MOSFET is provided to prevent excessive reverse current. When the overcurrent duration exceeds the preset time, intermittent protection will be triggered. When the die temperature exceeds the thermal shutdown temperature, the thermal discontinuity protection function will disable the device and re-enable the component after the built-in thermal discontinuity time.

| NAME | NO. | I/O(1) | DESCRIPTION |
|---|---|---|---|
| BOOT | 13 | I | A bootstrap cap is required between BOOT and PH. The voltage on this cap carries the gate drive voltage for the high-side MOSFET. |
| COMP | 8 | O | Error amplifier output, and input to the output switch current comparator. Connect frequency compensation to this pin. |
| EN | 10 | I | Enable pin. Float to enable. Adjust the input undervoltage lockout with two resistors. |
| GND | 2, 3 | G | Return for control circuitry and low-side power MOSFET. |
| PH | 11, 12 | O | The switch node. |
| PVIN | 4, 5 | P | Power input. Supplies the power switches of the power converter. |
| PWRGD | 14 | G | Power Good fault pin. Asserts low if output voltage is low due to thermal shutdown, dropout, overvoltage, EN shutdown or during slow start. |
| RT/CLK | 1 | I | Automatically selects between RT mode and CLK mode. An external timing resistor adjusts the switching frequency of the device; In CLK mode, the device synchronizes to an external clock. |
| SS/TR | 9 | O | Slow start and tracking. An external capacitor connected to this pin sets the internal voltage reference rise time. The voltage on this pin overrides the internal reference. It can be used for tracking and sequencing. |
| VIN | 6 | P | Supplies the control circuitry of the power converter. |
| VSENSE | 7 | I | Inverting input of the gm error amplifier. |
| Exposed Thermal PAD | 15 | G | Thermal pad of the package and signal ground and it must be soldered down for proper operation. |
(1) I = input, O = output, G = GND, P = Power
