产品概述 返回TOPzyk嘉泰姆

          CXLE81115 CXLE81115A is a step-up DC/DC converter that delivers an accurate constant current for driving LEDs. Operating at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated current set by the external resistor. The CXLE81115 CXLE81115A is ideal for driving up to eight white LEDs in series or up to 30V.
