VAS1210
HBLED Driver for High Current Applications
General Description
Features
The VAS1210 is a step-down constant-current high-brightness LED (HBLED) drivers provide a cost-effective solution for exterior lighting, architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination applications.
The device operates from a 5V to 40V input range. The device drivers an external NMOS and can provide an externally adjustable output current up to 5A.
The device is well suited for applications requiring a wide input voltage range. The high-side current-sensing and an integrated current setting circuitry minimize the number of external components while delivering an LED current with ±5% accuracy.
