LM2575IN

Texas Instruments · DC-DC Converters · PDIP-16

LM2575IN from Texas Instruments, in a PDIP-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 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
2 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
3 OUTPUT output Switch output of the integrated 1-A driver that feeds the inductor and catch diode; the internal diode from output to VIN means the device gives no reverse-current protection.
4 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
5 GND power_in Ground pin; all ground pins must be connected to ground, and all ground pins must be soldered to wide PCB copper traces for low-inductance connections.
6 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
7 FEEDBACK input Output voltage sense input that must be connected between the two programming resistors, each less than 100 kΩ and placed close to the regulator, with a reference of 1.23 V.
8 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
9 ON/OFF input Active-low enable: ground it or apply a low-level TTL voltage (typically below 1.6 V) for normal operation, apply a high-level TTL or CMOS voltage for standby (about 50 µA), and never leave it open.
10 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
11 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
12 GND power_in Ground pin; all ground pins must be connected to ground, and all ground pins must be soldered to wide PCB copper traces for low-inductance connections.
13 GND power_in Ground pin; all ground pins must be connected to ground, and all ground pins must be soldered to wide PCB copper traces for low-inductance connections.
14 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
15 NC unconnected Not connected internally; the pin can be tied to the circuit ground plane to improve thermal performance.
16 VIN power_in Input supply pin rated 4.75 V to 40 V (absolute maximum 42 V), to be bypassed with a capacitor CIN of at least 47 µF placed close to the pin.
