24v switch 12v 6A; buck 8A dc / dc power supply ic; 36v buck 24v 4A; 36v switch 12v 6A; 40v turn 19v4A; 8A built-in MOS power IC; content: AL4008 is 180KHz fixed frequency PWM DC / DC converter, capable of 8A load high frequencies. Low ripple, excellent line and load adjustment. A minimum number of external original regulator simple to use, including internal frequency compensation and a fixed frequency oscillator. PWM control circuit can adjust from 0 to 100% duty cycle. Built-in current protection. When a power failure protection function is activated, the operating frequency from 48kHz to 180kHz reduction. Built-in internal compensation block is used to reduce the number of external components.
