QX5241 Overview
QX5241 is a step-down high-brightness LED constant-current driver with high accuracy. A high-side current-sense resistor adjusts the output current, which minimizes the number of external ponents while delivering an LED current with ±1% accuracy, and a dedicated PWM input (DIM) makes a wide range of pulsed dimming feasible. A hysteretic control algorithm ensures excellent input-supply rejection and fast response to...
