LM22680 2A SIMPLE SWITCHER®, Step-Down Voltage Regulator with Features December 12, 2008 LM22680 2A SIMPLE SWITCHER®, Step-Down Voltage Regulator .. with Features General Description The LM22680 series of regulators are monolithic integrated circuits which provide all of the active functions for a stepdown (buck) switching regulator capable of driving up to 2A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low ON-resistance N-channel MOSFET. The SIMPLE SWITCHER® concept provides for an easy to use plete design using a minimum number of external ponents and National’s WEBENCH® design tool....
