General Description
The LM2575 series of monolithic integrated circuits provide all the active functions for a step-down (buck) switching regulator. Fixed versions are available with a 3.3V, 5V, 12V, fixed output. Adjustable versions have an output voltage range from 1.23V to 37V. Both versions are capable of driving a 1A load with excellent line and load regulation.These regulators are simple to use because they require a minimum number of external components and include internal frequency compensation and a fixed-frequency oscillator. The LM2575 series offers a high efficiency replacement for popular three-terminal adjustable linear regulators. It substantially reduces the size of the heat sink, and in many cases no heat sink is required. A standard series of inductors available from several different manufacturers are ideal for use with the LM2575 series. This
feature greatly simplifies the design of switch-mode power supplies.
Features
? 3.3V, 5V, 12V, and adjustable output versions
? Voltage over specified line and load conditions:
Fixed version: ±3 max. output voltage
Adjustable version: ±2 max. feedback voltage
? Guaranteed 1A output current
? Wide input voltage range: 4V to 40V
? Wide output voltage range 1.23V to 37V
? Requires only 4 external components
? 52kHz fixed frequency internal oscillator
? Low power standby mode IQ typically < 200μA
? 80 efficiency (adjustable version typically > 80)
? Uses readily available standard inductors
? Thermal shutdown and current limit protection
? 100 electrical thermal limit burn-in
Applications
? Simple high-efficiency step-down (buck) regulator
? Efficient pre-regulator for linear regulators
? On-card switching regulators
? Positive to negative converter (inverting Buck-Boost)
? Isolated Flyback Converter using minimum number of
external components
? Negative Boost Converter
