Texas Instruments · DC-DC Converters · WSON-10-EP(4x4)
LMR14030QDPRTQ1 from Texas Instruments, in a WSON-10-EP(4x4). 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 | BOOT | power_out | Bootstrap capacitor connection for high-side MOSFET gate driver, connect 0.1µF ceramic capacitor between BOOT and SW pins. |
| 2 | VIN | power_in | Power supply input pin, connect bypass capacitor CIN with short PCB trace to GND. |
| 3 | VIN | power_in | Additional power supply input pin for distributed current routing and reduced parasitic inductance. |
| 4 | EN | input | Enable input with internal pull-up current, pull below 1.2V to disable or leave floating to enable device. |
| 5 | RT/SYNC | input | Frequency selection via external resistor for 200kHz to 2.5MHz operation or external clock synchronization input. |
| 6 | SS | input | Soft start control pin with internal 3µA charging current, connect external capacitor to program startup ramp time. |
| 7 | FB | input | Feedback input from output voltage divider, compared to 0.75V internal reference for voltage regulation. |
| 8 | PGOOD | tri_state | Open-drain power good output indicating regulated voltage status, use 10kΩ to 100kΩ external pull-up resistor. |
| 9 | GND | power_in | System ground and signal return reference, must connect to PCB ground plane. |
| 10 | SW | output | Switch output to external inductor, transitions between 0V and VIN at programmed switching frequency. |
| 11 | Thermal Pad | power_in | Exposed thermal pad for die heat dissipation, must solder to PCB ground plane for thermal and electrical connection. |
