Introduction

AI Translation

OC5265 is a high-side current-sensing, buck-topology, high-accuracy, high-brightness LED constant-current driver controller with an integrated 60V power switch. Output current is set via a single external resistor, with a maximum output current of 1.2A and current sensing accuracy of ±3%; minimal external components are required. The inductor current control scheme employed in this system is known as inductor current hysteretic control mode, which provides very fast response to load transients, high rejection of input voltage variations, and an inductor current ripple of +/-20%.
