Introduction

AI Translation

The VAS1260 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 5V and 60V, and provides an externally adjustable output current of up to 1.2A. The VAS1260 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Output current can be adjusted below the set value, by applying an external control signal to the ‘ADJ’ pin. The device operates over the -40℃ to +85℃ temperature range and is available in SOT89-5 package.
