LM2675N-12

Texas Instruments · DC-DC Converters · PDIP-8

LM2675N-12 from Texas Instruments, in a PDIP-8. 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 CB passive Bootstrap capacitor connection for the high-side driver; Table 4-1 specifies a quality 470nF capacitor between CB and VSW.
2 NC unconnected No internal connection; leave unconnected.
3 NC unconnected No internal connection; leave unconnected.
4 FB input Feedback sense input that connects to the feedback divider midpoint for the adjustable version or directly to the output capacitor for fixed versions; the absolute maximum rating is -0.3 V to 14 V, and FB must not be shorted to ground while the regulator is enabled.
5 ON/OFF input Enable input where high enables the regulator and low (below about 1.4 V typical) puts it in shutdown; the absolute maximum rating is -0.1 V to 6 V.
6 GND power_in Power ground connected to system ground, which also serves as the ground return for CIN and COUT and should be kept close to CIN.
7 VIN power_in Supply input connected to the high-side FET collector that must stay within 6.5 V to 40 V (absolute maximum 45 V) and be bypassed by CIN placed close to the pin and GND.
8 VSW output Internal high-side FET source and switch node that connects to the inductor and the external diode cathode; the absolute maximum switch-to-ground voltage is -1 V.
