LM22675, Step-Down Voltage Regulator

The LM22675 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 1A loads with excellent line and load regulation characteristics.

High efficiency (>90%) is obtained through the use of a l

LM22675 Features

* such as external component calculation, electrical simulation, thermal simulation, and Build-It boards for easy design-in. The switching clock frequency is provided by an internal fixed frequency oscillator which operates at 500 kHz. The LM22675 series also has built in thermal shutdown, current lim
