EL7563C Product details

General Description
The EL7563C is an integrated, full-featured synchronous step-down 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 EL7563C operates at a constant frequency pulse width modulation (PWM) mode, making external synchronization possible. Patented onchip resistorless current sensing enables current mode control, which provides cycle-by-cycle current limiting, over-current protection, and excellent step load response. The EL7563C 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 EL7563C ideal for desktop and portable applications.
