LM2678T-5.0/NOPB Datasheet

DC/DC Switching Converters


The LM2678 series( LM2678T-5.0/NOPB ) of regulators are monolithic integrated circuits which provide 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 series consists of fixed output voltages of 3.3V, 5V and 12V and an adjustable output version. LM2678T-5.0/NOPB Features • Simple and Easy to Design with (Using Off-The-Shelf External Components)• 120 mΩ DMOS Output Switch• Efficiency Up to 92%• 50μA Standby Current When Switched OFF LM2678T-5.0/NOPB Applications • Simple to Design, High Efficiency (>90%) Step-Down Switching Regulators• Efficient System Pre-Regulator for Linear Voltage Regulators• Battery Chargers
