Description
The PT4115 is an inductive step-down converter with continuous conduction mode that is designed to efficiently drive single or multiple series linked LEDs from a voltage source higher than the total LED chain voltage.The PT4115 can produce more than 30 watts of output power depending on the supply voltage and additional components.
The PT4115 has a power switch as well as a high-side output current detecting circuit that employs an external resistor to determine the nominal average output current, as well as a dedicated DIM input that accepts either a DC voltage or a wide range of pulsed dimming signals.It can be used for making LCD TV backlighting,Automotive lighting,Illuminated signs, etc.
FEATURES
