MP1488DJ-LF-Z from Monolithic Power Systems, in a TSOT-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 | SW | output | Power switch output that is the drain of the internal MOSFET, connected to the power inductor and output rectifier, and it can swing between GND and 25V. |
| 2 | GND | power_in | Ground pin; the datasheet gives no further limits for it beyond serving as the current sense return for FB. |
| 3 | FB | input | Feedback input that regulates the voltage across the external current sense resistor between FB and GND to 104mV, with the bottom of the LED string connected to FB. |
| 4 | EN | input | Regulator on/off control where a high input turns the converter on and a low input turns it off, and the pin cannot be left floating. |
| 5 | OV | input | Over-voltage input that measures the output voltage for open-circuit protection, connected to the top of the LED string, with the part shutting down if the output exceeds 28V. |
| 6 | IN | power_in | Input supply pin that must be locally bypassed, with an operating input voltage range of 2.5V to 6V. |
