# ZTP7192T

**ZILLTEK** · DC-DC Converters · TSOT-23-6L

ZTP7192T from ZILLTEK, in a TSOT-23-6L. 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 | GND | power_in | Ground reference pin for the regulator, which should be connected to a large copper area for heat spreading. |
| 2 | SW | power_out | Power switching output node that drives the output LC filter, with absolute maximum ratings of -0.3V to VIN+0.3V (-5V for under 10ns, 21V for under 10ns on the high side). |
| 3 | IN | power_in | Power input supplying the IC and the step-down switches, specified for a supply range of 4.5V to 18V with an absolute maximum of +19V. |
| 4 | FB | input | Feedback input that senses the output voltage through a resistive divider, with the feedback threshold set to 0.8V. |
| 5 | EN | input | Enable input that turns the regulator on when driven high and off when driven low, with an absolute maximum of -0.3V to VIN. |
| 6 | BOOT | input | High-side gate drive boost input that requires a 0.1μF or greater capacitor from SW, with an absolute maximum of VSW-0.3V to VSW+6V. |
