产品概述 返回TOPjoH嘉泰姆
The CXLE8190 is a step-up DC/DC converter designed for driving the white LEDs with an externally programmable constant current. This device features integrated, 38V power MOSFET that is capable of driving up to 10 white LEDs in series, providing inherent current matching for uniform brightness. WLED brightness adjustment is easily achieved via a single wire interface, totally 32 brightness levels of LED Dimming.joH嘉泰姆
The CXLE8190 features a variety of protection circuits, including integrated over-voltage protection (OVP), soft-start, cycle-by-cycle current limiting, and thermal shutdown protection circuitry.joH嘉泰姆
The CXLE8190 has 1A current limit. It is available in Green TDFN-2×2-8L package. It operates over an ambient temperature range of -40℃</span>to +85℃</span>.joH嘉泰姆
