The LM2676S-5.0/NOPB is a SIMPLE SWITCHER® 3A low component count Step-down Regulator, monolithic integrated circuit 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.
● Efficiency up to 94%
● Simple and easy to design (using off-the-shelf external components)
● 150mR DMOS Output switch
● 50µA Standby current when switched OFF
● ±2% Maximum output tolerance over full line and load conditions
● 260kHz Fixed frequency internal oscillator
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
