Texas Instruments LM2678S-5.0/NOPB Buck (Step Down) Switching Regulator Fixed 8V-40V In 5V And 5A Out 260 kHz TO-263-7

The 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
• 50?A Standby current when switched OFF
• ?2% Maximum output tolerance over full line and load conditions
• 260kHz Fixed frequency internal oscillator
