An external shutdown connection selects operating or standby modes. Heat sinks are generally unnecessary due the regulator’s high efficiency.

Switching Frequency Max kHz. These devices are available lm5274 fixed output voltages of 3. Circuits constructed around the LM use a standard series lm2574 datasheet inductors which are available from several different manufacturers.

The Datasjeet is available in 3. Because of lm2574 datasheet high efficiency, the copper traces on the printed-circuit board PCB are normally the only heat sinking needed.
