QX5241 High-side Sense High-brightness LED Driver
General Description
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 load transients and PWM dimming. QX5241 Features a 20% inductor current ripple and operates up to 1MHz switching frequency.
QX5241 is well suited for applications requiring a wide input voltage range from...
