MP1484 from JSMSEMI, in a ESOP-8. 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 | BS | passive | Bootstrap pin; a capacitor connected between SW and BS is required to form a floating supply across the high-side switch driver. |
| 2 | IN | power_in | Power supply pin; recommended input voltage 4.5V to 18V (absolute maximum 20V). |
| 3 | SW | power_out | Switching pin connecting to the inductor; absolute maximum -0.3V to VIN+1V. |
| 4 | GND | power_in | Ground pin. |
| 5 | FB | input | Adjustable version feedback input; connect FB to the center point of the external resistor divider (absolute maximum 6V). |
| 6 | NC | unconnected | No connection (no function listed in the datasheet table). |
| 7 | EN | input | Drive to a logic-high to enable the IC; drive to a logic-low to disable the IC and enter micro-power shutdown mode (absolute maximum 20V). |
| 8 | NC | unconnected | No connection. |
| 9 | EPAD | power_in | Exposed pad, ground pin. |
