Qorvo's ACT6358 is a step-up DC/DC converter that is used to drive white LEDs with an externally programmable constant current. The device features integrated 40 V power MOSFETs that are capable of driving up to ten white LEDs in series, providing inherent current matching for uniform brightness. WLED brightness adjustment is easily achieved via a dual-function pin, which accepts either a PWM or an analog dimming control signal.
该产品具有多种保护电路，包括集成过电压保护（OVP）、可编程软启动、逐周期限流和热关机保护电路。产品的电流限制为1A。
行动6358is available in a small 3mm x 3mm 8-pin TDFN33-8 package.
典型应用
- TFT LCD显示器
- 智能手机
- 便携式媒体播放器
- GPS/个人导航设备
