Monolithic Power Systems · LED Drivers · TSOT-23-5
MP3302DJ-LF-Z from Monolithic Power Systems, in a TSOT-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 | SW | power_out | Power switch output, the drain of the internal MOSFET, which connects to the power inductor and output rectifier and can swing between GND and 36V. |
| 2 | GND | power_in | Ground pin, which must be connected to the GND plane for proper device operation and thermal performance. |
| 3 | FB | input | Feedback input that regulates the voltage across the LED current sense resistor between FB and GND to a 200mV reference, with the bottom of the LED string connected to FB. |
| 4 | EN | input | ON/OFF control and dimming command input where above 0.6V turns the part on, below 0.4V turns it off, and 0.7V to 1.4V sets FB regulation between 0V and 200mV. |
| 5 | IN | power_in | Input supply pin with a recommended supply range of 2.5V to 6V, which must be locally bypassed. |
