The LM2676S-12/NOPB is a step-down Voltage Regulator provides all of the active functions for a step-down (buck) switching 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 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. The LM2676 series also has built in thermal shutdown, current limiting and an on/off control input that can power down the regulator to a low 50µA quiescent current standby condition. The output voltage is ensured to a ±2% tolerance. The clock frequency is controlled to within a ±11% tolerance.
● Efficiency up to 94%
● Simple and easy to design with (using off-the-shelf external components)
● Internally limited power dissipation
● 150mR DMOS output switch
● 50µA Standby current when switched off
● ±2% Maximum output tolerance over full line and load conditions
● Green product and no Sb/Br
