H8116A28NR
Shanghai Siproin Microelectronics · DC-DC Converters · SOT-23
H8116A28NR from Shanghai Siproin Microelectronics, in a SOT-23. 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 | VOUT | power_out | Output voltage pin; the VOUT pin voltage is rated VSS-0.3 V to VSS+8 V. |
| 2 | Vss | power_in | GND pin, which is the reference for the VOUT, EN and LX pin voltage ratings. |
| 3 | LX | output | External inductor connection pin; the LX pin voltage is rated VSS-0.3 V to VSS+8 V and the LX pin current is rated 1000 mA, and the built-in MOSFET is turned off by a protection circuit if the LX voltage exceeds the limit. |
