MSKSEMI · DC-DC Converters · SOT-23-6
MP2359DJ-LF-Z-MS from MSKSEMI, in a SOT-23-6. 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 | GND | power_in | Ground pin, to be connected to a large copper area for thermal performance per the PCB layout guidance. |
| 3 | FB | input | Adjustable-version feedback input; connect FB to the center point of the external resistor divider (regulated feedback voltage 0.791 V to 0.823 V). |
| 4 | 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. |
| 5 | IN | power_in | Power supply pin; input voltage range is 4 V to 30 V per the electrical characteristics. |
| 6 | SW | output | Switching pin, the switch node driving the inductor. |
