    VAS1210P 规格书说明书

    General Description

    The VAS1210P is a step-down constantcurrent 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 7V to 60V 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 highside 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.
