LMR10530XSD

Texas Instruments · DC-DC Converters · WSON-10-EP(3x3)

LMR10530XSD from Texas Instruments, in a WSON-10-EP(3x3). 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 VINC power_in Input supply for internal bias and control circuitry. Need to locally bypass this pin to GND.
2 EN input Enable control input. Logic high enables operation. Do not allow this pin to float or subject to voltages greater than VIN + 0.3V.
3 SGND power_in Signal (analog) ground. Place the bottom resistor of the feedback network as close as possible to this pin for good load regulation.
4 NC unconnected No user function, connect this pin to GND.
5 FB input Feedback pin. Connect this pin to the external resistor divider to set output voltage.
6 PGND power_in Power ground pin. Provides ground return path for the internal driver.
7 SW output Switch pin. Connect this pin to the inductor and catch diode.
8 SW output Switch pin. Connect this pin to the inductor and catch diode.
9 VIND power_in Input supply voltage. Connect a bypass capacitor locally from these pins to PGND.
10 VIND power_in Input supply voltage. Connect a bypass capacitor locally from these pins to PGND.
11 DAP passive Exposed pad (from the footprint; not named in the datasheet pin table).
