LMR54410DBVR

Texas Instruments · DC-DC Converters · SOT-23-6

LMR54410DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CB output Bootstrap capacitor connection for high-side FET driver; connect 100nF high-quality ceramic capacitor from this pin to SW pin.
2 GND power_in Power ground pin connected to low-side FET source; connect to system ground and ground side of CIN and COUT with shortest path to CIN.
3 FB input Feedback input to converter for output voltage regulation; connect resistor divider from VOUT to set output voltage and never short this terminal to ground during operation.
4 EN input Precision enable input controlling converter ON/OFF (high = on, low = off); do not float, can be tied to VIN, voltage must not exceed VIN + 0.3V, enables adjustable UVLO by external resistor divider.
5 VIN power_in Supply input pin for internal bias LDO and high-side FET with input range 4V to 36V (withstands 50V short transients); connect to input supply and input bypass capacitors directly to this pin.
6 SW output Switching output of converter internally connected to source of high-side FET and drain of low-side FET; connect to external power inductor.
