艾睿:
Thanks to Texas Instruments&s; synchronous buck LM2748MTC/NOPB DC voltage controller, you&s;ll be able to accurately increase or decrease the DC voltage within your electronic circuit. This DC voltage controller has single output. Its output produces a current of 20 A. With an output that has a voltage of 0.6 to 13.5 V, this is power management at its best. This DC voltage controller has an input voltage of 1 to 17 V. It has a switching frequency of 50 to 1000 kHz. In order to ensure parts aren&s;t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This DC voltage controller has an operating temperature range of -40 °C to 125 °C.
