TLV61225DCKR

Texas Instruments · DC-DC Converters · SC-70-6

TLV61225DCKR from Texas Instruments, in a SC-70-6. 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 VIN power_in Boost converter input voltage, operating range 0.7 V to 3.3 V, with a 10-µF ceramic capacitor recommended close to VIN and GND.
2 FB input Output voltage sense input that must be connected directly to VOUT for the fixed 3.3-V output.
3 GND power_in Control, logic and power ground.
4 VOUT power_out Boost converter output voltage, fixed 3.3 V (3.13 V to 3.43 V), with abs max rating of 7.5 V.
5 L passive Connection for the inductor, placed between VIN and L (4.7 µH typical, current rating of 400 mA or higher recommended).
6 EN input Enable input (high enabled, low disabled) that must be actively tied high or low and not left floating.
