Introduction

AI Translation

FM4115K is a continuous inductor current conduction mode step-down constant current source designed to drive one or more series-connected LEDs. The input voltage range is 6V to 30V, with adjustable output current up to 1.2A. Depending on the input voltage and external components, it can drive LEDs up to tens of watts. The device integrates a power switch, uses high-side current sensing to set the LED average current, and accepts both analog dimming and wide-range PWM dimming via the DIM pin. When the DIM voltage falls below 0.3V, the power switch turns off and the device enters a standby state with ultra-low operating current. Available in SOT89-5 package.
