Introduction

AI Translation

The PJL4115SR is a high-efficiency step-down LED driver controller with a wide input voltage range of 6V to 30V. It is designed to operate in continuous current mode. The PJL4115SR employs a hysteretic control architecture that accurately regulates LED current with a feedback coming from an external high-side current-sense resistor. This control scheme optimizes circuit stabilization and fast response time without loop compensation. Its low 200mV average feedback voltage reduces power loss and improves the converter’s efficiency. The PJL4115SR implements PWM and analog dimming together through the DIM pin. It also includes thermal overload protection in case of output overload.
