Product details

Description

The LM22673 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 3A loads with excellent line and load regulation characteristics.

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 LM22673 series also has built in thermal shutdown and current limiting. The current limit threshold can be adjusted using an external resistor. An adjustable soft-start feature is provided by selecting an appropriate external soft-start capacitor. Features.
