Monolithic Power Systems · DC-DC Converters · TSOT-23-8
MP3414AGJ-Z from Monolithic Power Systems, in a TSOT-23-8. 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 | IN | power_in | Power supply input whose start-up bias is derived from IN and must be bypassed locally, with bias moving to OUT once VOUT exceeds VIN. |
| 2 | OUT | power_out | Output at the drain of the internal synchronous rectifier MOSFET, which derives bias power from OUT when VOUT is higher than VIN and allows OUT to be disconnected completely from IN when EN is low, with the trace to the output filter capacitors kept as short and wide as possible. |
| 3 | SW | output | Power switch output connecting the internal low-side and synchronous MOSFETs, where the power inductor connects between SW and the input supply and the trace should be kept short and wide to reduce EMI and voltage spikes. |
| 4 | PGND | power_in | Power ground. |
| 5 | FTY | passive | Factory use only; leave floating or connect it to ground in the application. |
| 6 | AGND | power_in | Analog ground. |
| 7 | FB | input | Feedback input to be connected to the tap of an external resistive voltage divider from the output, which sets the output voltage. |
| 8 | EN | input | Chip enable control input that turns the regulator on when set higher than 1.2V and turns it off when set lower than 0.4V. |
