DESCRIPTION
The LM22676 series of regulators are monolithic integratedcircuits which provide all of the active functions for a stepdown (buck) switching regulator capable of driving up to 3Aloads with excellent line and load regulation characteristics.High efficiency (>90%) is obtained through the use of a lowON-resistance N-channel MOSFET. The series consists of afixed 5V output and an adjustable version.
The SIMPLE SWITCHER concept provides for an easy touse complete design using a minimum number of externalcomponents and National's WEBENCHe design tool.National's WEBENCHe tool includes features such as exter-nal component calculation, electrical simulation, thermal sim-ulation, and Build-lt boards for easy design-in. The switchingclock frequency is provided by an internal fixed frequency oscillator which operates at 500 kHz. The LM22676 series alsohas built in thermal shutdown, current limiting and an enablecontrol input that can power down the regulator to a low 25UA quiescent current standby condition.
