LM22676MRE-ADJ

Texas Instruments · DC-DC Converters · SOIC-8-EP

LM22676MRE-ADJ from Texas Instruments, in a SOIC-8-EP. 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 BOOT input Bootstrap input for high-side N-FET gate driver; typical 10nF ceramic capacitor required between BOOT and SW pins; absolute maximum voltage VSW + 7V.
2 NC unconnected No electrical connection; may function as thermal conductor.
3 NC unconnected No electrical connection; may function as thermal conductor.
4 FB input Feedback input to regulator for closed-loop output voltage control; reference voltage 1.285V (typ) for -ADJ version; absolute maximum voltage 7V.
5 EN input Precision enable input for regulator control; supply >2.2V (typ) to enable, <1.6V (typ) to disable; internal 6µA pullup; absolute maximum voltage 6V.
6 GND power_in Ground input to regulator; system common reference.
7 VIN power_in Input supply voltage to regulator; recommended operating range 4.5V to 42V; absolute maximum 43V.
8 SW output Switching output of regulator; rectangular waveform between 0V and VIN at 500kHz switching frequency.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
