General Description
The LM2574 family is a series of easy to use fixed and adjustable switching voltage regulators. The LM2574 contains all of the active circuitry necessary to construct a stepdown (buck) switching regulator and requires a minimum of external components.
Features
? 3.3V, 5V, 12V, and adjustable output versions
? Adjustable version output 1.23V to 37V ±4 max. over line and load conditions.
? Guaranteed 0.5A output current
? Wide input voltage, up to 40V
? Thermal shutdown and current limit protection
? Requires only 4 external components.
? Shutdown capability (standby mode)
? Low power standby mode < 200μA Typical
? High-efficiency
? 52kHz fixed frequency internal oscillator
? Uses standard inductors
Applications
? Simple high-efficiency step-down (buck) regulator
? Efficient pre-regulator for linear regulators
? On-card switching regulators
? Positive to negative converter (buck-boost)
