EL7563CRE集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

EL7563CRE属于集成电路（IC）的稳压器-DC-DC开关稳压器。由瑞萨科技有限公司制造生产的EL7563CRE稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。

Monolithic 4 Amp DC/DC Step-Down Regulator

The EL7563 is an integrated, full-featured synchronous stepdown regulator with output voltage adjustable from 1.0V to 2.5V. It is capable of delivering 4A continuous current at up to 95 efficiency. The EL7563 operates at a constant frequency pulse width modulation (PWM) mode, making external synchronization possible. Patented on-chip resistorless current sensing enables current mode control, which provides cycle-by-cycle current limiting, over-current protection, and excellent step load response. The EL7563 features power tracking, which makes the start-up sequencing of multiple converters possible. A junction temperature indicator conveniently monitors the silicon die temperature, saving the designer time on the tedious thermal characterization. The minimal external components and full functionality make this EL7563 ideal for desktop and portable applications.
