Magnachip半导体公司已发布了用于多种应用的同步增压转换器,例如SSD,OLED面板和蓝牙扬声器的NAND Flashes。

新的同步增压转换器配备了快速瞬态响应,以减少稳定电源的短响应时间的输出电压波动。因此,新产品非常适合设备,可以表现出明显的当前变化。

这个新发布的转换器的关键特性sa reduction in quiescent current of up to 1.5 mA, as compared to the maximum 2 mA of asynchronous boost converters currently on the market. Magnachip achieves this metric by the adoption of low-resistance high-side and low-side synchronous switches. Also, when a boost converter turns off, a built-in isolation switch prevents input voltage from being leaked through the output pin. And the soft-start time can be programmable by controlling the external capacitor and resistance values. This action reduces the in-rush current and ensures a stable power supply to external circuits.

该同步升压转换器还提供了强电流和过电压保护,热关闭,快速放电功能以及在小型双扁平无线线套件中的电压锁定功能(DFN)为2.5- x 2.5毫米的强电路保护功能。它以1.2 MHz的开关频率工作,因此可以外部连接具有低容量的小型4.7 µH电感器。结果,PCB的大小也将减小。

In addition, its packaging technology meets halogen-free requirements and also complies with the Restriction of the Use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) – another example of Magnachip’s commitment to deliver environmentally-friendly and sustainable semiconductor products.

Magnachip首席执行官YJ Kim说:“在过去的10年中,Magnachip开发了广泛的电视,照明,显示面板,移动设备和IT设备的电源解决方案。”“基于我们久经考验的技术能力,我们将继续纳入各种功能,例如雄鹿,增压,多通道,运算放大器,并将ICS交换为产品,并扩展我们的下一代综合电源管理产品组合。”
