Introduction

AI Translation

UMW PT4115 is a step-down constant current source operating in continuous inductor current conduction mode, designed to drive one or more series-connected LEDs. The PT4115 accepts an input voltage range of 6V to 30V with an adjustable output current of up to 1.2A. Depending on the input voltage and external components, the PT4115 can drive LEDs with total power of up to tens of watts. The PT4115 integrates a power switch and uses high-side current sensing to set the average LED current. Via the DIM pin, it supports both analog dimming and wide-range PWM dimming. When the DIM pin voltage falls below 0.3V, the power switch turns off and the PT4115 enters a standby state with extremely low operating current.
