LM2678S-5.0/NOPBThe 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., Efficiency up to 92%, Simple and easy to design (using off-the-shelf external components), 120mR DMOS Output switch, 50µA Standby current when switched OFF, ±2% Maximum output tolerance over full line and load conditions, 260kHz Fixed frequency internal oscillatorМикросхемы / Микросхемы управления питанием / Импульсные преобразователи Корпус: DDPAK/TO-263-7, инфо: IC REG BUCK 5V 5A TO263-7
