LM2678S-5.0/NOPB

Понижающий импульсный стабилизатор, фиксированный, 8В-40В (Vin), 5В и 5A на выходе, TO-263-7.

The LM2678S-5.0/NOPB is a SIMPLE SWITCHER® high efficiency 5A Step-down Voltage Regulator, monolithic integrated circuit provides all of the active functions for a step-down (buck) switching regulator capable of driving up to 5A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low ON-resistance DMOS power switch. The SIMPLE SWITCHER concept provides for a complete design using a minimum number of external components. A high fixed frequency oscillator (260kHz) allows the use of physically smaller sized components. A family of standard inductors for use with the LM2678 are available from several manufacturers to greatly simplify the design process.
