LM2576-12WT規(guī)格書詳情
General Description
The LM2576 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, or 12V fixed output. Adjustable versions have an output voltage range from 1.23V to 37V. Both versions are capable of driving a 3A load with excellent line and load regulation.
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 3A 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
