消耗电流 meaning in English

current sinking

The driver has the quiescent current under 1 a and also has soft - start circuitry to limit inrush current flow at power up . the chip can be operated normally in the temperature range of - 40 to 85 according to the simulation results . the brightness of the white leds can be controlled by using a dc voltage or a pwm signal applied to the pin with a few external components added
系统采用0 . 5 mcmos工艺;输入电压范围为2 . 7v到5 . 5v ;在关闭状态下消耗电流小于1 a ;具有软启动功能,可减小启动过程中的浪涌电流;具有短路及过热保护功能,工作温度范围为- 40至85 ; led亮度控制可以通过外加dc或pwm电压信号和很少的外部元件实现。
