HIGH EFFICIENCY PWM BUCK LED DRIVER CONTROLLER
DESCRIPTION
The UTC ULD3380 is a PWM mode step-down converter. By
well controlling the external MOSFET and regulating a constant
output current. The output duty cycle of the UTC ULD3380 can
be up to 100% for wider input voltage application.
The UTC ULD3380 is available in a SOT-26 package.
