SP433 Datasheet, PDF (1/10 Pages) SYNC POWER Crop. – Constant Voltage and Constant Current Controller

SP433
Constant Voltage and Constant Current Controller
DESCRIPTION
The SP433 is high-voltage four-terminal adjustable
voltage references, with over current protection
feature. The SP433 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.
SP433 is idea for low cost switching power supply
application.
