Introduction

AI Translation

PT4123E is a step-down constant current driver operating in continuous inductor current conduction mode, designed to drive one or more series-connected LEDs. The PT4123E input voltage range spans from 6V to 60V, with an adjustable output current of up to 6A. Depending on the input voltage and external components, the PT4123E can drive LEDs up to tens of watts.

The PT4123E integrates an internal power switch, uses high-side current sensing to set the average LED 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 PT4123E enters a standby state with extremely low operating current.
