Introduction

AI Translation

PT4115-TD is a step-down constant-current LED driver operating in continuous inductor current conduction mode, designed to drive one or more series-connected LEDs. It accepts an input voltage range of 8V to 40V with an adjustable output current of up to 1.2A. Depending on the input voltage and external components, the device can drive LEDs up to tens of watts. PT4115-TD integrates an internal power switch and uses high-side current sensing to set the average LED current. It supports both analog dimming and wide-range PWM dimming via the DIM pin. When the DIM pin voltage falls below 0.3V, the power switch turns off and the device enters a standby state with ultra-low quiescent current. PT4115-TD is available in SOT89-5 and SOT23-5 packages.
