Introduction

AI Translation

PT4115 is a buck regulator for dimmable LED drivers, designed in continuous current mode, capable of driving high-brightness LEDs from a wide input voltage range of 8.0V to 30V. The device employs a hysteretic control scheme to regulate LED current, providing optimized loop stability and extremely fast response time. PT4115 implements both PWM and analog dimming functions on the EN/DIM pin. The device incorporates undervoltage lockout and thermal overload protection to prevent damage during output overload conditions. PT4115 requires minimal standard external components and is available in a space-saving SOT89-5 package.
