TLV61047DDCR

Texas Instruments · IC · SOT-23-5

TLV61047DDCR from Texas Instruments, in a SOT-23-5. 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 SW passive Switch pin of the converter, connected to the drain of the internal power MOSFET; rated -0.3V to 32V.
2 GND power_in Ground.
3 FB input Voltage feedback of output voltage, connected to the center tap of a resistor divider to program the output voltage; rated -0.3V to 6V.
4 EN input Enable logic input where logic high enables the device and logic low disables it into shutdown mode; rated -0.3V to 20.5V.
5 VIN power_in IC power supply input, operating range 2.6V to 20V and rated -0.3V to 20.5V.
