Shanghai Siproin Microelectronics · DC-DC Converters · SOT-23-5
H8118A30M5R from Shanghai Siproin Microelectronics, in a SOT-23-5. 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 | EN | input | Shutdown pin: H enables normal operation and L stops step-up, with VSH min 0.75V and VSL max 0.3V at the LX pin. |
| 2 | VOUT | power_out | Output voltage pin; absolute maximum VOUT pin voltage is VSS-0.3V to VSS+8V. |
| 3 | NC | unconnected | Not connected (N.C.) internally. |
| 4 | GND | power_in | Ground pin for the device. |
| 5 | LX | passive | External inductor connection pin for the internal switching MOSFET; absolute maximum LX pin voltage is VSS-0.3V to VSS+8V and LX pin current is 1000 mA. |
