TPS54626PWPR from Texas Instruments, in a HTSSOP-14-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VO | power_out | Connect to output of converter; also used for the output discharge function. |
| 2 | VFB | input | Converter feedback input; connect with a feedback resistor divider from VO. |
| 3 | VREG5 | power_out | 5.5V internal linear regulator output for control circuitry; a typical 1uF capacitor should be connected to GND; not active when EN is low. |
| 4 | SS | passive | Soft-start control pin; an external capacitor connected to GND sets the soft-start ramp time (6uA typical charge current). |
| 5 | GND | power_in | Signal ground pin for the control circuitry. |
| 6 | PG | output | Open-drain power-good output; requires an external pull-up resistor (25k-150kOhm) to VREG5. |
| 7 | EN | input | Enable control input, active high; must be pulled up to enable the device (internal pull-down resistance to GND of 200-800kOhm). |
| 8 | PGND1 | power_in | Ground return for the low-side MOSFET; also serves as an input to the current comparator; connect strongly to GND near the IC. |
| 9 | PGND2 | power_in | Ground return for the low-side MOSFET; also serves as an input to the current comparator; connect strongly to GND near the IC. |
| 10 | SW1 | output | Switch node connection between the high-side and low-side NFETs; also serves as an input to the current comparator. |
| 11 | SW2 | output | Switch node connection between the high-side and low-side NFETs; also serves as an input to the current comparator. |
| 12 | VBST | passive | Supply input for the high-side NFET gate driver (boost terminal); connect a capacitor from this pin to the SW1/SW2 terminals; an internal PN diode connects VREG5 to this pin. |
| 13 | VIN1 | power_in | Power input, connected to the high-side NFET drain. |
| 14 | VIN2 | power_in | Power input, connected to the high-side NFET drain; an additional 0.1uF capacitor from this pin to ground is recommended to improve stability of the over-current limit function. |
| 15 | PowerPAD | power_in | Exposed thermal pad on the package backside, internally connected to PGND; must be soldered to the PCB ground plane to achieve appropriate power dissipation. |
