Productomschrijving
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
