LM2576-12WT Maximum Output Current, Microchip, LM2576-12WT Adjustable Switching Regulator, 1-Channel 3A 5-Pin, TO-220

Microchip Technology Switching Regulator
The Microchip Technology TO-220 package type is a through-hole mount, 1 channel adjustable switching regulator with 5 pins. These monolithic integrated circuits provide all the active functions for a step down (buck) switching regulator. Adjustable versions have an output voltage range is between 1.23V and 37V.
Features and Benefits
100% electrical thermal limit burn in 52kHz fixed frequency internal oscillator 80% efficiency (adjustable version typically 80%) Adjustable version: ±2% max. Feedback voltage Fixed version: ±3% max. Output voltage Guaranteed 3A output current Low power standby mode IQ typically 200μA Requires only 4 external components Thermal shutdown and current limit protection Uses readily available standard inductors Voltage over specified line and load conditions is Wide input voltage range: 4V to 40V
Applications
Efficient pre-regulator for linear regulators Isolated flyback converter using minimum number of external components Negative boost converter On card switching regulators Positive to negative convertor (inverting Buck-Boost) Simple high-efficiency
