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
