LM2676S-ADJ/NOPB, Регулятор напряжения понижающий, 3А, Uвх=8-40В, Uвых=1.2-37В [DDPAK-7]
The LM2676S-ADJ/NOPB is a step-down switching Voltage Regulator, capable of driving up to 3A 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 series consists of fixed output voltages of 3.3, 5 and 12V and an adjustable output version. 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 LM2676 are available from several manufacturers to greatly simplify the design process.
