VAS1210——HBLED Driver for High Current Applications

General Description
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. A novel control algorithm ensures excellent input-supply rejection and fast response during load transients and PWM dimming. The devices operate up to 1MHz switching frequency, thus allowing for small component size

The device operate over the -40°C to +85°C temperature range and available in SOT23-6L
