STANSON TECHNOLOGY
ST8433 (Pb-Free)
Constant Voltage and Constant Current Controller
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.
