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.
LM SIMPLE SWITCHER 4V to 40V, A Step-Down DC/DC Switching Regulator |
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator.
A standard series of inductors optimized for l2m574 with the Lm2574 datasheet are available from several different manufacturers. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Sampling Lm2574 datasheet Pricing Options.
