LM2676S-ADJ/NOPB Datasheet PDF - TI

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.

● Efficiency up to 94%

● Simple and Easy to Design with (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, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
