LMR14006YDDCR

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

LMR14006YDDCR from Texas Instruments, in a TSOT-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 passive Bootstrap capacitor connection between this pin and SW pin; stores and supplies 4V to 6V bias voltage for internal high-side MOSFET gate drive.
2 GND power_in Ground connection; signal and power return path for internal circuits and external components.
3 FB input Feedback input for output voltage regulation; set VOUT = 0.765V × (1 + R1/R2) using external resistor divider with input range 0V to 5.5V.
4 /SHDN input Active-low enable input; pull below 1.25V typical rising threshold (1.05V to 1.38V range) to disable or leave floating to enable; high voltage tolerant to 40V.
5 VIN power_in Power supply input; 4V to 40V operating range supplies internal circuits and serves as drain connection for internal high-side MOSFET.
6 SW output Switch node output; connects to external inductor, Schottky diode, and bootstrap capacitor; drives up to 600mA peak switching current with voltage swing of -1V to 45V.
