LM22671 500 mA SIMPLE SWITCHER®, Step-Down Voltage Regulator with Features October 17, 2008 LM22671 500 mA SIMPLE SWITCHER®, Step-Down Voltage .. Regulator with Features General Description The LM22671 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 500 mA 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 series consists of a fixed 5V output and an adjustable version. The SIMPLE SWITCHER® concept provides for an easy to use plete design using a...
