Description
The LM2574 series of regulators are monolithic integrated circuits ideally suited for easy
and convenient design of a step–down switching regulator (buck converter).
All circuits of this series are capable of driving a 0.5 A load with excellent line and load regulation.
These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version.
These regulators were designed to minimize the number of external components to simplify the power supply design.
Standard series of inductors optimized for use with the LM2574 are offered by several different inductor manufacturers.
Since the LM2574 converter is a switch–mode power supply,
its efficiency is significantly higher in comparison with popular three–terminal linear regulators,
especially with higher input voltages. In most cases, the power dissipated by the LM2574 regulator is so low,
that the copper traces on the printed circuit board are normally the only heatsink needed
and no additional heatsinking is required.
The LM2574 features include a guaranteed ±4% tolerance on output voltage
within specified input voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to +125°C).
External shutdown is included, featuring 60 µA (typical) standby current.
The output switch includes cycle–by–cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
