The LM family is a series of easy to use fixed and adjustable switching voltage regulators. The LMxx series lj2574 regulators are monolithic integrated circuits that provide all the active functions for a step-down buck switching regulator, capable of driving a 0.
Shutdown lm2574 datasheet standby mode Low power standby mode High efficiency 52kHz fixed frequency internal oscillator Uses standard inductors View More. An external shutdown connection selects operating or standby modes. The LM contains all of the active circuitry necessary to construct a stepdown buck switching regulator and requires a minimum of external components.
Adequate heat transfer is usually provided by soldering all package pins to a printed circuit board.
The LMxx series offers a high-efficiency replacement for popular three-terminal linear regulators. The lm2574 datasheet switch includes cycle-by-cycle current limiting, as well as thermal lm2574 datasheet for full protection under fault conditions.

Because of its high efficiency, the copper traces on the printed-circuit board PCB are normally the only heat sinking needed. Description The LMxx series of regulators are lm2574 datasheet integrated circuits that lm2574 datasheet all the active functions for a step-down buck switching regulator, capable of driving a 0.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. Please contact sales office if lm2574 datasheet weight is not available. LM – 52 kHz Lm2574 datasheet 0. The LM is available in 3.
lm2574 datasheet This feature greatly simplifies the design of switch-mode power supplies. Heat sinks are generally unnecessary due the regulator’s high efficiency.
