LM2575S-3.3

Понижающий импульсный стабилизатор, фиксированный, 4В-40В (Vin), 3.3В и 1A на выходе, TO-263-5.

The LM2575S-3.3 is a SIMPLE SWITCHER® 1A Step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. This device is available in 3.3V of fixed output voltage and requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2575 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink and in many cases no heat sink is required. A standard series of inductors optimized for use with the LM2575 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies.
