HT26993D-ADJ from HTCSEMI, in a DFN-6-EP(2x2). 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 pin, connected to GND as the common reference for the device. |
| 2 | VOUT | output | Boost converter output; the datasheet requires a ceramic output capacitor placed as close to the VOUT and GND pins as possible. |
| 3 | FB | input | Voltage feedback input for the adjustable output voltage; connect a resistive divider to program the desired output, with a typical FB voltage of VREF = 1.0V. |
| 4 | EN | input | Device enable input; a logic high enables the device and a logic low disables it and fully disconnects the output from the input. |
| 5 | SW | output | Switch node, the drain connection of the low-side power MOSFET, rated at 6.0V maximum to GND. |
| 6 | VIN | power_in | Power supply input with an operating input voltage range of 0.9V to 5.2V and an absolute maximum of 6.0V to GND. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
