TPS54613PWPR

Texas Instruments · DC-DC Converters · HTSSOP-28-EP

TPS54613PWPR from Texas Instruments, in a HTSSOP-28-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 AGND power_in Analog ground and return for the slow-start capacitor, VBIAS capacitor and RT resistor; it must be connected to the PowerPAD.
2 VSENSE input Error amplifier inverting input that must be connected directly to the output voltage sense point.
3 NC unconnected No connection.
4 PWRGD output Open-drain powergood output that is high-Z when VSENSE is at or above 90% of Vref and low otherwise, and is also low when SS/ENA is low or internal shutdown is active.
5 BOOT power_out Bootstrap input; a 0.022-µF to 0.1-µF low-ESR capacitor connected from BOOT to PH generates the floating drive for the high-side FET driver.
6 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
7 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
8 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
9 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
10 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
11 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
12 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
13 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
14 PH output Phase node at the junction of the internal high-side and low-side power MOSFETs and the output inductor; all PH pins should be tied together and routed to the output inductor.
15 PGND power_in Power ground and high-current return for the low-side driver and power MOSFET, to be connected with large copper areas to the input and output supply returns.
16 PGND power_in Power ground and high-current return for the low-side driver and power MOSFET, to be connected with large copper areas to the input and output supply returns.
17 PGND power_in Power ground and high-current return for the low-side driver and power MOSFET, to be connected with large copper areas to the input and output supply returns.
18 PGND power_in Power ground and high-current return for the low-side driver and power MOSFET, to be connected with large copper areas to the input and output supply returns.
19 PGND power_in Power ground and high-current return for the low-side driver and power MOSFET, to be connected with large copper areas to the input and output supply returns.
20 VIN power_in Input supply for the power MOSFET switches and internal bias regulator, operating from 3 V to 6 V and to be bypassed to PGND with a low-ESR 1-µF to 10-µF ceramic capacitor placed close to the package.
21 VIN power_in Input supply for the power MOSFET switches and internal bias regulator, operating from 3 V to 6 V and to be bypassed to PGND with a low-ESR 1-µF to 10-µF ceramic capacitor placed close to the package.
22 VIN power_in Input supply for the power MOSFET switches and internal bias regulator, operating from 3 V to 6 V and to be bypassed to PGND with a low-ESR 1-µF to 10-µF ceramic capacitor placed close to the package.
23 VIN power_in Input supply for the power MOSFET switches and internal bias regulator, operating from 3 V to 6 V and to be bypassed to PGND with a low-ESR 1-µF to 10-µF ceramic capacitor placed close to the package.
24 VIN power_in Input supply for the power MOSFET switches and internal bias regulator, operating from 3 V to 6 V and to be bypassed to PGND with a low-ESR 1-µF to 10-µF ceramic capacitor placed close to the package.
25 VBIAS power_out Internal bias regulator output supplying the internal circuitry, to be bypassed to AGND with a high-quality low-ESR 0.1-µF to 1-µF ceramic capacitor; absolute maximum source current is 6 mA.
26 SS/ENA input Dual-function slow-start and enable pin that provides a logic input to enable or disable operation and a capacitor input to externally set the start-up time; absolute maximum voltage is 7 V.
27 FSEL input Frequency select logic input that chooses between two internally set switching frequencies; absolute maximum voltage is 7 V.
28 RT input Frequency-setting resistor input; connect a resistor from RT to AGND to set the switching frequency; absolute maximum voltage is 6 V.
29 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
