LM2594N-ADJ

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-40В (Vin), 1.2В-37В, 500мА, DIP-8.

The LM2594N-ADJ is a SIMPLE SWITCHER® step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation. Requiring a minimum number of external components, this regulator is simple to use and feature internal frequency compensation, a fixed-frequency oscillator and improved line and load regulation specifications. The LM2594xx series operates at a switching frequency of 150kHz, thus allowing smaller-sized filter components than what would be needed with lower-frequency switching regulators. Because of its high efficiency, the copper traces on the printed-circuit board are normally the only heat sinking needed. A standard series of inductors (both through-hole and surface-mount types) are available from several different manufacturers optimized for use with the LM2594xx series. This feature greatly simplifies the design of switch-mode power supplies.
