LM2575-12YN

The LM2575 series of monolithic integrated circuits provide all the active functions for a step-down (buck) switching regulator. Adjustable versions have an output voltage range from 1.23V to 37V. These regulators are simple to use because they require a minimum number of external components 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. 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. The feedback voltage is guaranteed to ±2% tolerance for adjustable versions, and the output voltage is guaranteed to ±3% for fixed versions, within specified input voltages. The feedback voltage is guaranteed to ±2% tolerance for adjustable versions, and the output voltage is guaranteed to ±3% for fixed versions, within specified input voltages and output load conditions. External shutdown is included, featuring less than 200?A standby current. The output switch includes cycle-by-cycle current limiting and thermal The output switch includes cycle-by-cycle current limiting and thermal shutdown for full protection under fault conditions.
