LM22680 - National Semiconductor

LM22680 Step-Down Voltage Regulator

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® conc.
