UMW PT4115 is a step-down and constant current source with continuous inductor current conduction mode, which is used to drive one or more LEDs in series.The input voltage range of PT4115 is from 6V to 30V, and the output current is adjustable, up to 1.2A.Depending on the input voltage and external devices, PT4115 can drive LEDs up to tens of watts.
PT4115 has built-in power switch. It uses high-end current sampling to set the average LED current. Through the dim pin, it can accept analog dimming and a wide range of PWM dimming.When the voltage of dim is lower than 0.3 V, the power switch will be turned off and PT4115 will enter the standby state of extremely low working current.
