LM2651MTCX-ADJ

Texas Instruments · DC-DC Converters · TSSOP-16

LM2651MTCX-ADJ from Texas Instruments, in a TSSOP-16. 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 output Switched-node connection, connected to the source of the internal high-side MOSFET.
2 SW output Switched-node connection, connected to the source of the internal high-side MOSFET.
3 VIN power_in Main power supply pin; the recommended supply voltage range is 4 V to 14 V, with an absolute maximum of 15 V.
4 VIN power_in Main power supply pin; the recommended supply voltage range is 4 V to 14 V, with an absolute maximum of 15 V.
5 VIN power_in Main power supply pin; the recommended supply voltage range is 4 V to 14 V, with an absolute maximum of 15 V.
6 VCB input Bootstrap capacitor connection for high-side gate drive.
7 AVIN power_in Input supply voltage for control and driver circuits.
8 SD(SS) input Shutdown and soft-start control pin; pulling it below 0.3 V shuts off the regulator, a capacitor to ground sets the input-current control ramp, and it must not be driven by an external source.
9 FB input Output voltage feedback input, connected to the output voltage; absolute maximum feedback pin voltage is −0.4 V to 5 V.
10 COMP input Compensation network connection, connected to the output of the voltage error amplifier.
11 NC unconnected No internal connection.
12 AGND power_in Low-noise analog ground.
13 AGND power_in Low-noise analog ground.
14 PGND power_in Power ground.
15 PGND power_in Power ground.
16 PGND power_in Power ground.
