TMI3113H2D from TMI, in a DFN-8-EP(2x2). 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 | FB | input | Output voltage feedback pin; an internal resistive divider scales the output voltage for comparison to the internal 0.6V reference (regulated feedback voltage 0.588V to 0.612V in PWM). |
| 2 | PG | output | Power good open-drain output that goes high impedance when the output is above 91% of the regulated nominal voltage and is pulled low when it falls below that threshold; power good sink current is 2mA. |
| 3 | IN | power_in | Analog supply input, operating over 2.7V to 5.5V with input UVLO at 2.5V rising and input OVP at 6.1V typical. |
| 4 | GND | power_in | Ground pin. |
| 5 | NC | unconnected | Labeled NC in the DFN2x2-8 top view; the pin description table does not list this pin. |
| 6 | LX | output | Power switch output connected to the inductor and to the drains of the internal P-channel and N-channel MOSFETs; absolute maximum LX voltage is -0.3V to 7V (-2.5V to 7.5V for under 10ns transients). |
| 7 | EN | input | Enable pin: drive above 1.5V to turn the part on and below 0.4V to turn it off; do not leave EN floating. |
| 8 | GND | power_in | Ground pin (the pin description table lists GND at DFN pins 4 and 8). |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
