DESCRIPTION

The ST8433 is high-voltage four-terminal adjustable voltage references, with over current

protection feature. The ST8433 is a one chip solution to a 2.5V precision voltage reference

and constant current output in the application of secondary feedback control of power

supply, DC/DC converter, adaptor and charger. ST8433 is idea for low cost switching

power supply application.
